Troubleshoot Common Problems Encountered When Editing ObjectScript with VS Code
This page provides solutions to problems which you may encounter while using the InterSystems® ObjectScript Extension Pack for Visual Studio Code (VS Code) to develop ObjectScript-based applications.
Cannot Save Routine: Illegal Header Line, ROUTINE Header Is Required
When you save or update a file to an InterSystems server using the InterSystems ObjectScript extension for VS Code, the extension invokes the InterSystems IRIS® source code file REST API’sOpens in a new tab PutDoc methodOpens in a new tab. The PutDoc method requires the first line of a routine file to be a header which identifies the file contents as routine code. For the ObjectScript routine file testroutine.inc, this header would take the following form:
ROUTINE testroutine [Type=INC]
The Type keyword can also specify MAC or INT. If no Type is specified, MAC is assumed by default.
If you attempt to save or update a routine which does not include the ROUTINE header, the save operation fails with the error message ERROR #5001: Illegal Header Line.
When you use an editor to view the contents of a routine file which does not include the ROUTINE header, the InterSystems Language Server for VS Code decorates the code with a ROUTINE header is required CodeLens link. Select the link and the Language Server extension will add the header for you.
