This operation can only be performed in stateful mode

Hello all!

I would like to change an object using the setObjectSource method. When calling the method, I receive the following error message:

"This operation can only be performed in stateful mode".

How can I switch the mode to stateful?

Thanks,
Chris

Sample code from unit tests (note that the creation needs to be done from a stateless client, and that you might need to specify a transport number):

    try {
      await c.createObject({
        description: "temporary test program",
        name,
        objtype: "PROG/P",
        parentName: "$TMP",
        parentPath: "/sap/bc/adt/packages/$TMP"
      })
      c.stateful = session_types.stateful
      const handle = await c.lock(path)
      // write the program
      await c.setObjectSource(main, source, handle.LOCK_HANDLE)
      // read it
      const newsource = await c.getObjectSource(main)
      expect(newsource).toMatch(/Hello,World!/m)
      // delete
      await c.deleteObject(path, handle.LOCK_HANDLE)
      await c.unLock(path, handle.LOCK_HANDLE)
    } finally {
      c.dropSession()
    }
