Does it cause issue if my training attribute is polynomial while testing attribute is nominal?

I have encountered "java.lang.NullPointerException" error when running "explain predictions" operator.
These are some of the warning message which I found at the log:

Nov 17, 2020 4:31:23 AM WARNING: MetaCost: The value types between training and application differ for attribute 'ACTIVITY TYPE', training: polynominal, application: nominal
Nov 17, 2020 4:31:23 AM WARNING: SimpleDistribution: The value types between training and application differ for attribute 'ACTIVITY TYPE', training: polynominal, application: nominal

Would these cause issue or the error I encountered is possibly due to other reasons?
