Describe the bug

An AttributeError occurs in allocate_gen_fuel_by_generator_energy_source.

Bug Severity

How badly is this bug affecting you?

• High: This bug is preventing me from using PUDL.

To Reproduce

pt = pudl.output.pudltabl.PudlTabl(
    sqlalchemy.create_engine(pudl.workspace.setup.get_defaults()["pudl_db"]),
    freq="AS",
    fill_fuel_cost=True,
    roll_fuel_cost=True,
    fill_net_gen=True,
)
df = pt.gen_fuel_by_generator_energy_source_eia923()

When running this code I get the following error:

Software Environment?

• Operating System. macOS 12.6.1
• Python version and distribution 3.10.6 | packaged by conda-forge | (main, Aug 22 2022, 20:41:22) [Clang 13.0.1 ]
• How did you install PUDL?
  • using pip from GitHub (catalystcoop.pudl @ git+https://github.com/catalyst-cooperative/pudl.git@dev) giving 0.6.1.dev1034+g50bbc573.
  • I am using the pudl.sqlite that I downloaded today, running a sha256 checksum on it gives e7975672303d8ad3a423cf80e9d15273b6e11171c40182f76dd6bda1f53272d4.

Hmm. I'm not able to reproduce this error, also on python 3.10.6, having just downloaded the PUDL DB from yesterday with the same sha256 sum. I wonder what's different.
