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?

Yeah... Theoretically it shoul be no real deal but they are not the same. Best way to solve this is to add a nominal to text followed by a text to nominal operator, this way all your nominals and polynominals are 'equalized' to nominal...5
