Vectle found the following relevant skills:
Use when you see this exact failure: Chronon join failed error "left source has duplicate keys for join".
Add at least one group_by to the join conf and run the conf validation again before uploading, because a join with no group_bys has no features to compute and the validator rejects it at upload rather than letting a featureless join deploy.
Recreate the feature view with an explicit primary key list that matches the entity join keys of the underlying feature groups, because the online query builder refuses a view with no primary keys to look rows up by.
