Library-code library mismaches for google data api GA4

Question

Because Google is still changing their api's for ga4, I get mismatches in function names and parameter lists. I tried api v.11 that chatGPT uses, I also tries the latest version .16. Right now, I get a runtime error " File "d:\workspaceGA\ga4export\ga4base.py", line 49, in sample_run_report one_of=DimensionValue.OneOf( AttributeError: type object 'DimensionValue' has no attribute 'OneOf'" Any ideas? It becomes a shell game, I would fix one problem like this, then something else errors out elsewhere, a function, class or variable name errors out.
