"Could not create stream" - OpenAI integration issue

The community member is encountering an error when trying to use the OpenAI integration in their self-hosted Typebot application, specifically the error message "Could not create stream". Other community members suggest that the issue may only occur in the preview and not in production, and that the chat stops working even in the published bot. The logs show that the failure happens at the /api/v2/sessions/[session-id]/streamMessage endpoint, which returns a 500 error, while the /continuChat endpoint is working fine. The request to the failing endpoint has an unusually small content-length of 2 bytes, which may be related to the issue. The solution was found by a community member, who discovered that the ENCRYPTION_SECRET values in the docker-compose.yml file were different between the builder and viewer services, causing AES cipher failures due to an encryption key mismatch, preventing proper data encryption/decryption between the services.
