Root cause is installation of databroker 2.0.0b40 in the workflow.

Project dependencies:

hklpy/pyproject.toml

Lines 50 to 59 in 782b8ae

	dependencies = [
	"apischema",
	"databroker",
	"numpy",
	"ophyd",
	"pint",
	"pygobject",
	"pyRestTable",
	"tqdm",
	]

Workflow installs Python with these additional dependencies:

hklpy/.github/workflows/conda_unit_test.yml

Lines 44 to 48 in 782b8ae

	create-args: >-
	coveralls
	pytest
	pytest-cov
	python=${{ matrix.python-version }}

Could pin databroker=1.2 in the workflow.
