Validation returns a missing_attribute error message.

A mandatory attribute is missing

A component lacks an attribute - the one named in the message - that is compulsory.

For example, an operation must have service and fields attributes.


  1. On the Canvas panel, select the component that contains the error.
  2. Depending on the missing attribute, either:
    • Enter a value for the attribute in the Edit view of the Settings panel
    • Drag-and-drop a service or a field at the component
