How to fix validator cache error in dash app? When I callback app, it returns this type of error. Please see attach image. It works correctly, when I refresh page. suggest me any python or dash library to remove this error.
i have been experiencing the same error lately.
It might have something to do with the updates that came with python 3.9.
I havent looked too deep into the modules but it could be connected to the change they made with “importlib”.
It works fine with python 3.8, thats the only “fix” i found so far.
You are right.I reinstalled python 3.8 and it worked correctly.
