Workflow source file not found

Error message

Workflow source file not found: ${normalizedFilePath}

What it means

readWorkspaceSourceFile returned null from readWorkspaceFile, meaning the normalized path does not exist inside the runtime workspace — the workflow source file being bound (or refreshed after save) is missing, so its content and hash cannot be produced.

Solutions

  1. Verify the file path and that the file was written to the workspace before binding
  2. Re-create or re-save the workflow source file, then retry the binding operation
Defensive patterns

Strategy: validation
