Vision assistant returns error "Image pattern4: not an image"

Hi,

 

I use vision assistant (with LV2022Q3)to do some pattern matching and OCR on a customer label. Very rarely the vision assistant VI throws an error saying: Image pattern4 not an image.

 

This time I have probed the img source and img destination inputs of the express VI and saved those images. (all the other inputs of the VI are constants). Then I have stopped my app and executed the express VI with loading the previously saved images. No error occured, it did everything as expected so the error is not reproducible even if the inputs are the same.

 

Is there a known issue like this with the Vision Assisant VI? (besides that "you should not use express VIs, you need to build your own stuff from elementary functions" which wont help too much here)

 

thanks!
