Problems with aiida 2.7 version

[alinzh]

I run crystal calculations using mpds_aiida (by yascheduler). And i am getting an error with aiida version == 2.7.
An excerpt from my script:

inputs = AiidaStructureWorkChain.get_builder()
inputs.metadata = dict(label=label)
inputs.structure = DataFactory('structure')(ase=atoms_obj)

It is important to note that it works on lower versions (tested on aiida 2.5).
@akvatol @knopki please pay attention.
