The documentation for the lookup plugin, community.mongodb.mongodb, was malformed.
The errors were:
1 validation error for PluginDocSchema doc -> __root__ Cannot specify dict_keys(['lookup']) if `name` has been specified. (type=value_error)
File a bug with the community.mongodb collection in order to have it corrected.
