The error was caused by
(d *DatabaseManager) GetEntitiesWithFilename(filename string) ([]Entity, error)

Slice types other than byte slice are currently not supported.

Error message needs to be improved. #11950

@hyangah I've removed the only slice that I have. It cames from the method that you said, but the problem is still there:

Ok, finally I figure it out what's going wrong with the bindings:
