Model Comparison Internal Error

[ShrutiSuryawanshi]

Hi, I am trying to do a model comparison with a decision tree, forest model and linear regression and I'm getting an error of "Tool #3 Internal Error - Can not load MakeSnippetFromBlob: Blob does not appear to be an image. I tried a lot of things but I can't seem to find a solution to fix the error.
Please help :)

It's hard to tell which lines are going into the Union tool - can you confirm it's the O outputs of each predictive modeling tool?

Yes, I confirm I have added only the O (output) of the regression models to the Union tool.

Then it's a very odd error - are you willing to share the workflow so I can test it out myself?
