Solutions

1. Retry the create; the provider returned a source_ref that is not a flow version UUID. Report to the provider integration maintainer if reproducible.

When it happens

Trigger: Occurs when a created tool binding's source_ref is not a UUID where a flow version id was expected.

Common situations: See trigger scenarios.
