attachment_behavior not working for accessing remote files

[frieda-huang]

Hi, I ran the following examples in agents, but it looks like there is a problem with accessing the file content when executing

iterator = agent.execute_turn(
            [turn.message],
            turn.attachments,
        )

• podcast_transcript.py
• rag_as_attachments.py
• inflation.py

Output

For example, with podcast_transcript.py, I got the following output:

inference> I'd be happy to help you summarize the podcast transcript. 
Can you please provide me with the contents of the file at 
"/var/folders/2g/07kbk1350b98fd_msglwdr440000gn/T/tmp354ikrbz/CAMZO2Cjtranscript_shorter.txt"?

Inspecting further, it looks like the following code in common/execute_with_custom_tools.py is not returning the correct response.

response = self.client.agents.turn.create(
    agent_id=self.agent_id,
    session_id=self.session_id,
    messages=current_messages,
    attachments=attachments,
    stream=True,
)

I got the following in response.response.content:

'Traceback (most recent call last):\n  File "/Users/friedahuang/.vscode/extensions/ms-python.debugpy-2024.12.0-darwin-
arm64/bundled/libs/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_resolver.py", line 193, in _get_py_dictionary\n

The problem is due to the code here. I'm using pgvector for memory bank, but it is not able to retrieve that context from the upstream. Temp solution is to add provider_id="remote::pgvector" manually.

There is another problem in PGVectorIndex(EmbeddingIndex) here, it resulted in

pgvector/pgvector.py", line 60, in __init__
    self.cursor.execute(
psycopg2.errors.SyntaxError: syntax error at or near "-"
LINE 2: ...LE IF NOT EXISTS vector_store_memory_bank_b2acc8c5-5722-415b...

It could be fixed by using self.table_name = f"vector_store_{bank.identifier.replace('-', '_')}"

This is my yaml file:

Uh oh, thanks for the helpful details. I will take a look at this today and add a test so we don't break these things again.

Thanks for raising the issue! https://github.com/meta-llama/llama-stack/pull/264 - This should fix the first issue.
