Contact custom attributes filled in the pre-chat form (e.g. a CPF field)
were silently lost when the visitor's email or phone matched an existing
contact. The widget sent the attributes in a separate request that raced
the conversation create: creating the conversation merges the widget
contact into the existing contact, so the attribute update landed on the
destroyed contact and vanished without an error. New visitors were
unaffected, which made the bug hard to spot.
The fix sends contact custom attributes inside the same request that
identifies the contact. The widget conversation create endpoint now
accepts `contact.custom_attributes` and applies them through
`ContactIdentifyAction` in the same transaction as the merge, so the
submitted values always land on the surviving contact. The campaign path
folds the attributes into the existing contact update call the same way.

```ruby
# Concurrent reproduction of the pre-chat form race that loses contact
# custom attributes when the visitor's email matches an existing contact.
#
# The old widget fired two unawaited requests on pre-chat submit. Each
# iteration replays them as real concurrent threads:
# - create thread = POST /widget/conversations: resolves the widget contact,
# then runs ContactIdentifyAction (which merges the widget contact into the
# existing contact) inside a transaction held open while the conversation
# and message are created.
# - patch thread = PATCH /widget/contact: resolves the widget contact via its
# contact inbox and applies the custom attributes through
# ContactIdentifyAction, exactly like Widget::ContactsController#update.
#
# Run with: bundle exec rails runner confirm_prechat_race.rb
# Creates throwaway contacts on Account.first and deletes them afterwards.
ITERATIONS = 20
CPF = '123.456.789-09'.freeze
account = Account.first!
inbox = account.inboxes.first!
losses = 0
ITERATIONS.times do |i|
existing = account.contacts.create!(name: 'Existing Contact', email: "race-existing-#{SecureRandom.hex(6)}@example.com")
temp = account.contacts.create!(name: 'Widget Visitor')
contact_inbox = ContactInbox.create!(contact: temp, inbox: inbox, source_id: SecureRandom.uuid)
begin
create_request = Thread.new do
ActiveRecord::Base.connection_pool.with_connection do
widget_contact = ContactInbox.find(contact_inbox.id).contact # set_contact before_action
ActiveRecord::Base.transaction do
ContactIdentifyAction.new(
contact: widget_contact,
params: { email: existing.email, phone_number: nil, name: 'Widget Visitor' },
retain_original_contact_name: true,
discard_invalid_attrs: true
).perform
sleep(0.02) # conversation + message creation keeps the transaction open
end
end
end
patch_request = Thread.new do
ActiveRecord::Base.connection_pool.with_connection do
sleep(rand * 0.02) # network jitter between the two requests
widget_contact = ContactInbox.find(contact_inbox.id).contact # set_contact before_action
ContactIdentifyAction.new(
contact: widget_contact,
params: { custom_attributes: { cpf: CPF } },
discard_invalid_attrs: true
).perform
end
end
create_request.join
patch_request.join
survivor = existing.reload
if survivor.custom_attributes['cpf'] == CPF
puts "iteration #{i + 1}: CPF survived"
else
losses += 1
puts "iteration #{i + 1}: CPF LOST (survivor custom_attributes: #{survivor.custom_attributes.inspect})"
end
ensure
account.contacts.where(id: [existing.id, temp.id]).find_each(&:destroy!)
end
end
puts
puts "#{losses}/#{ITERATIONS} iterations lost the CPF -- race #{losses.positive? ? 'confirmed' : 'not reproduced in this run'}"
```
Result: **20/20 iterations lose the CPF** (consistent across repeated
runs). The conversation create holds its transaction open across the
contact merge, so the fast attribute update either resolves the
soon-to-be-destroyed widget contact or blocks on its row lock and then
updates 0 rows — silently, with no error. This is why the customer sees
the loss every time, not intermittently.
Note: the script replays the old two-request flow at the service layer,
so it reproduces the loss even with this fix applied — the fix works by
removing the second request from the widget, not by changing the raced
code paths. The new request spec (`saves contact custom attributes on
the surviving contact when merged into an existing contact`) covers the
fixed contract.

## Closes
- Reported via support conversation:
https://app.chatwoot.com/app/accounts/1/conversations/84465
## How to reproduce
1. Create a website inbox with a pre-chat form that has a contact custom
attribute field (e.g. CPF).
2. Create a contact with a known email address.
3. As a visitor, open the widget and fill the pre-chat form using that
same email plus a value for the custom attribute.
4. Before: the attribute never appears on the contact profile. After: it
is saved on the existing contact, overwriting any stale value.
## What changed
- `POST /api/v1/widget/conversations` now permits
`contact.custom_attributes` and passes it to `ContactIdentifyAction`,
which deep-merges it atomically with the contact merge.
- The widget pre-chat form sends contact custom attributes inside the
conversation create payload instead of a separate `setCustomAttributes`
call; the campaign path includes them in the `contacts/update` payload.
### Description
When integrating the web widget via the JS SDK, customers call
setConversationCustomAttributes and setLabel on chatwoot:ready — before
any conversation exists. These API calls silently fail because the
backend endpoints require an existing conversation. When the visitor
sends their first message, the conversation is created without those
attributes/labels, so the message_created webhook payload is missing the
expected metadata.
This change queues SDK-set conversation custom attributes and labels in
the widget store when no conversation exists yet, and includes them in
the API request when the first message (or attachment) creates the
conversation. The backend now permits and applies these params during
conversation creation — before the message is saved and webhooks fire.
### How to test
1. Configure a web widget without a pre-chat form.
2. Open the widget on a test page and run the following in the browser
console after chatwoot:ready:
`window.$chatwoot.setConversationCustomAttributes({ plan: 'enterprise'
});`
`window.$chatwoot.setLabel('vip');` // must be a label that exists in
the account
3. Send the first message from the widget.
4. Verify in the Chatwoot dashboard that the conversation has plan:
enterprise in custom attributes and the vip label applied.
5. Set up a webhook subscriber for `message_created` confirm the first
payload includes the conversation metadata.
6. Verify that calling `setConversationCustomAttributes` / `setLabel` on
an existing conversation still works as before (direct API path, no
regression).
7. Verify the pre-chat form flow still works as expected.
The UI displays only six articles, and this update introduces a per_page
parameter to control the number of articles returned per API call. The
value is capped between 1 and 100, with a default fallback if a lower
number is set.
This change is necessary due to high website traffic, where excessive
payloads are returned without adding value.
**Changes:**
- Add index to status, account_id, portal_id, views.
- Add per_page param in the API.
- Update the code in the frontend to fetch only 6
Due to the pattern `**/specs/*.spec.js` defined in CircleCI, none of the
frontend spec in the folders such as
`specs/<domain-name>/getters.spec.js` were not executed in Circle CI.
This PR fixes the issue, along with the following changes:
- Use vitest instead of jest
- Remove jest dependancies
- Update tests to work with vitest
