Unable to transform - Error messages

I'm using VPht Time Series and TransfromApplier reduce obs but with some targets I get error messages with VPhot.

Usually it's related to Airmass being incorrect.

Today I got a new one # Cannot transform ENSEMBLE: CREFMAG - CMAGINS is wrong.

I have changed various things like remove the number of "accidentals targets" and just keep intended. I think this worked once.

Sometimes I think it's because a B mag is missing for a comp.

Spending many hours trying to track it down.

Any hints please?
