Error Messages in SAP Business One Hana (Service Layer) Connector
The following errors are sometimes seen during workflow execution.
|An error has occurred on the request
|This is a generic error that indicates something has gone wrong while attempting to fetch “Workflow Message” or “Workflow Message Data” triggers.
|This error occurs when a connection cannot be made to Service Layer during “Workflow Message” or “Workflow Message Data” triggers.
|Empty Response from API
|This indicates that Service Layer responded, but with no data.
|RequestBody can’t be left blank
|This error is encountered when a map has not been configured, when a map is not used but “Request Body” field has been omitted, or when the result of a mapping is empty. To resolve this error, ensure mappings are configured or that a valid “Request Body” has been manually provided.
|(Action Technical Name) Stack trace
|A “Stack trace” message follows the action’s technical name when an unknown error has occurred. Investigate the issue by reviewing logged details found after the equals sign.
|U_SALTBOX_MESSAGES is not an EntitySet
|This error response occurs when Service Layer is unable to communicate with the Saltbox Query Extension installed in Hana Studio. When this error occurs, restart Service Layer.
