@dosubot[bot] commented on GitHub (Jan 2, 2025):

To resolve the AttributeError indicating that ToolEngineInvokeError has no attribute meta, ensure that when you are raising the ToolEngineInvokeError, you are passing the meta argument correctly. The ToolEngineInvokeError class is defined to accept a meta parameter in its constructor, which is then assigned to the instance attribute self.meta.

Here's an example of how you should raise this error:

from core.tools.errors import ToolEngineInvokeError
from core.tools.entities.tool_entities import ToolInvokeMeta

# Assuming you have a ToolInvokeMeta instance
meta_instance = ToolInvokeMeta(...)

try:
    # Some code that might fail
    pass
except SomeException as e:
    raise ToolEngineInvokeError(meta=meta_instance) from e

Ensure that ToolInvokeMeta is correctly imported and instantiated before passing it to ToolEngineInvokeError. If meta is not provided or incorrectly passed, it will result in an AttributeError [1].

What's your expected behavior? I am not quite understand what you are trying to make here.
If you get an error, and the program report an error, I figure this is expected right?

@crazywoola
There is a problem with the tool call request. The program will be handed over to the big model to continue executing. Now, running e.meta will display an error: AttributeError: 'ToolEngineInvokeError' object has no attribute 'meta', causing the program to not run further.
