Power Automate errors / Schema
Resource not found for the segment '<EntitySetName>'.
Cause
A Dataverse action references an entity set name or custom process action that is incorrect, misspelled, or inactive.
Fix
Confirm the logical collection (plural) name by opening the table in a Solution > See solution layers. Use the exact logical collection name (e.g. cr123_customentities, not 'Custom Entities'). If it is a custom process action, verify it is Active under Settings > Processes. Re-save and test.
