ht400 callback error - licenced api

[viafrotaapp-ops]

For the past few days, among my 3 apis runing, the one with the licence key is giving me a headache!
Every message sent via chatwoot is promptly proceced and delivered to whatsapp but on the first request chatwoot always returns 400 (even with the messagem correctly sent), and you presse update or "resend", the delivered mark sets to ok and no more error!

Only wih the session with licence key, all callback requests returns 400 on the firt request....

Anybody has ever had the same trouble?

I am running the callbacks on host.docket:3001/chatwoot, one port for each session and for each inbox, same config for all of them, for that reason I dont think the problema is on the server side!

Just noticed on the rails logs:

• it sure is something on open-wa!

=>nil, :event=>"message_updated"}, :api_inbox_webhook worker-1 | I, [2025-09-08T14:01:03.622518 #1] INFO -- : [ActiveJob] [WebhookJob] [1fbd57c1-a7b9-41b8-a969-84b467360c34] Performing WebhookJob (Job ID: 1fbd57c1-a7b9-41b8-a969-84b467360c34) from Sidekiq(medium) enqueued at 2025-09-08T14:01:03Z with arguments: "http://host.docker.internal:3001/chatwoot", {:account=>{:id=>1, :name=>"VIAFROTA"}, :additional_attributes=>{}, :content_attributes=>{"external_error"=>"400 Bad Request"}, :content_type=>"text", :content=>"hoje", :conversation=>{:additional_attributes=>{}, :can_reply=>true, :channel=>"Channel::Api", :contact_inbox=>#<GlobalID:0x00007f2c84c81e20 @uri=#<URI::GID gid://chatwoot/ContactInbox/8>>,

Chatwoot is getting the error from open-wa.... but message is sent, delivered!
