I have all the Scenarios in error using OPENAI (Message an assistant)
Assistant is set to USE v2 and apikey is new.
[400] The v1 Assistants API has been deprecated. Please try again by setting the header ‘OpenAI-Beta: assistants=v2’. See the migration guide for more information: https://platform.openai.com/docs/assistants/migration.
And i cannot change HEADERS on the “Message an assistant” Module.
The same here.
Looks like the setup in make is still using the V1 connection and then just adding V2 as default in the header.
Hi Rasmus, could you assist us in setting v2 as the default since the current default is v1 for this module?
Hello everyone @here
I just want to step in and let you know that this issue occurred due to some undocumented changes on OpenAI’s end. Our development team is currently working on a hotfix, which will be deployed soon. We will keep you updated with any progress.
We are very sorry for any inconvenience and disruption this is causing.
Thank you very much for you patience and understanding while we work to resolve this. 
Estoy en la misma situación, gracias Michaela. Aguardamos! Saludos
I’m in the same situation, thank you, Michaela. We’ll wait! Regards.
Hey y’all,
Hope this post finds you well!
I’m trying to use the message assistant module, but I found a problem with the API version:
i’ve already checked my assistants and they’re on V2, i also tried to creating another API key and doesn’t work.
Has anyone else encountered this problem?
Any solutions?
yes i have the same problem today.
Hey Olivier,
check this out: OpenAI Message an assistance ERROR: [400] The v1 Assistants API has been deprecated - #2 by Rasmus_Stouby
It seems that the development team already knows about this issue
OpenAI announced back in April that this change was coming yesterday. Do we have an update on when the Make.com devs plan to deploy this hotfix?
Hello everyone @here
I wanted to let you know that our dev team has confirmed that the hotfix was successfully deployed, so everything should be up and running now.
If you’re still experiencing any issues, please open a support ticket with the Care Team who will help further investigate this.
Once again, we apologize for any trouble this has caused.
Thank you very much for your patience and understanding.
Hello @Said_Ait_ouakour, thank you very much for reporting back.
I’m truly sorry to hear that you’re still experiencing this issue. Could you please try adding the “Message an Assistant” module again? Just make sure your module does not say “Deprecated”.
Thanks a lot for your cooperation
Thanks It’s working 
I’m happy to hear that, thanks a lot for confirming
Happy holidays!
