I may be completely off here and this is common knowledge to everyone but me… If so, I am sorry. But I have hade some strange errors in my installation, such as:
DiscourseAi::Completions::Endpoints::Anthropic: status: 400 - body:
{
“type”:“error”,
“error”:{“type”:“invalid_request_error”,
“message”:“This model does not support assistant message prefill. The conversation must end with a user message.”},“request_id”:“req_011CcqMN6eswEfRHPmQmPLC4”
}
Which was strange since most other AI-related stuff worked. This happened primarly with my summarizer and with search as in:
https://..../forum/discourse-ai/embeddings/semantic-search?q=search_term
Which gave a 500 ERROR.
When I checked logs I got:
{
"type": "error",
"error": {
"type": "invalid_request_error",
"message": "This model does not support assistant message prefill. The conversation must end with a user message."
},
"request_id": "req_011CcqQvXPAHSfvoUeu92gf9"
}
I traced this back to Content Create-persona
And the error seems to be this part:
because when I removed it (which wasn’t possible on this specific persona) by doing a clone and setting this setting to my clone
Semantic search started to work. I needed to do a similar thing in e.g. my summarizer.
Is this something you guys experienced as well?
