I’m debugging a Dify tool plugin that I’m currently developing.
Even though it had been working without any issues, when I stop the debug run, make a small change (in a part unrelated to the tool’s parameters), and run the debug again, I frequently encounter the following error:
1 validation error for ToolInput
type
Value error, value must be a list [type=value_error, input_value='variable', input_type=str]
For further information visit https://errors.pydantic.dev/2.11/v/value_error
I haven’t changed anything about the parameters passed to the tool.
Is there any way to investigate what’s actually happening?
It says “You can check the logs on the trace screen,” but I don’t know what the trace screen refers to.
