Filtering on custom attributes that are expressions

[pierre]

Hey, we rely on lots of custom attributes that are in fact expressions, based on math operations on some other custom attributes or built-in attributes.

Since we recently jumped to latest ftrack version ( we were on 3.something before) , we realized that filtering on those "expressions-custom attributes" was no longer working and generating a server error instead.

 

Is it the expected behaviour or dp we have some underlying issue?

We can workaround using api-like query filters but is is mostly duplicate code.
