ArcGIS API for Python: AttributeError: module 'brotli' has no attribute 'error'

GZOlehana — Wed, 15 Dec 2021 18:08:32 GMT

from arcgis.gis import GIS

when run in ArcGIS Pro 2.6 notebook results in long error message (below).

What might be wrong?

Note that import arcpy works without difficulties.

Did it ever work or is this just recent?

What version of the python api?

Did you upgrade the arcgis module recently?
