failed to call sdk module generate client: %w

Error message

failed to call sdk module generate client: %w

What it means

The dagql select of the SDK module's generateClient field failed after all arguments (modSource ID, introspection JSON ID, outputDir) were prepared. This is the actual SDK-side client generation failure — runtime container error, SDK bug, or rejected inputs.
