REST API query returns no geometry for complex polygons

[KellyChan]

Enterprise 10.7.1 query doesn't return any geometry if the polygon is complex (very many vertices.) This occurs when requesting f=pbf. But, of course, featurelayer defaults to pbf these days. How can we fix/work around this

No geometry

Many rings

Can you elaborate on "very many vertices"?  And, did this work in previous versions of ArcGIS Enterprise?  Also, does it work if you change the output format?

[KellyChan]

haven't pin point the threshold number of vertices which breaks the query.

yes, work from earlier version

yes, work with f=json/xml

[JoshuaBixby]

can you share either a polygon that has the issue or create a sample/example that shows the same issue?
