[REQUIRED] Step 3: Describe the problem

Duplicate of internal bug b/330838846, more details provided there

Customer installed the Firebase extension "Chatbot with Gemini", and it initially functioned correctly, but after a while, it stopped working entirely ,and all function calls failed with the error message: "ClientError: [VertexAI.ClientError]: got status: 400 Bad Request." [1].

Questions:

• What could be causing this error?
• Is there any way to see more detail on the Bad Request error? Is the API returning any more detail than that?
• How should context be provided when using this extension?

[cabljac]

do we have access to their config, and any details on the input?

Context can either be provided in the config, or (if overrides are configured on) in the parent doc of the chat collection (needs to be a subcollection in this case)

e.g if you put "act like a pirate" in the config parameter context and your collection path was chats/{cid}/messages

then you put "don't act like a pirate" in the context field of the document chats/123, in theory it shouldn't respond like a pirate
