The AgentLoader previously attempted to access
e.msg
on exceptions encountered during agent loading. This caused a crash when the exception was apydantic_core._pydantic_core.ValidationError
from Pydantic v2+, as this error type does not have amsg
attribute.This commit modifies the exception handling in
AgentLoader
's_load_from_module_or_package
and_load_from_submodule
methods to usestr(e)
instead ofe.msg
. This ensures that the error message is correctly retrieved for all exception types, including Pydantic v2ValidationError
.A new test case has been added to specifically verify this scenario by simulating a Pydantic v2 style error during agent loading. Existing tests for other error types (SyntaxError, NameError) within agent code have been updated to reflect the new
RuntimeError
wrapping behavior of the AgentLoader.Fixes #1227
