How can we resolve this error when we try to run a test in the classification rule builder? 

Error message: The test timed out. Try reducing the number of keys and try again. If the problem continues, please contact technical support

Hi @user70977 

can you add screenshots of the rule you are testing, meaning the regex?

I agree, understanding what you are trying to test will help us to see if we can replicate the error..

I have never seen this particular error before.
