The Invalid Argument Value error is issued in the following situations:
The literal ‘<argument value>’ set in the ‘WebReferenceName’ argument of the action ‘<actionName>’ does not match any Web Service name consumed in the eSpace.: some actions have parameters that receive the name of Web Services consumed by the eSpace. The name you supplied does not exist in the eSpace.
To fix this, check whether the Web Service is being consumed or the name is correct, because the Web Service does not exist in the eSpace.
Clicking the symbol will take you directly to the argument of the action where the violation occurs.
