Hi @finnbergquist @rahul1 we are facing trouble trying to use PATCH on a Observation valueString .

const response = await medplum.patchResource(
    'Observation',
    '12345',
    [
      {
        op: 'add',
        path: '/value',
        value: 'test',
      },
    ]
  );

this is what we are currently trying to do , we get a success response but doesn't seem to make the changes on the resource . what we actually need is to patch multiple observations using a batch operation . regards, Charith V

@charithv , I believe the right

path

here would be to use

/valueString

Hi Rahul , this works thanks . we were a little confused with the syntax for bundle request where we need to

JSON.stringify

or enclose with a string for 'valueString' but overall it works .

parameter: [
            {
              name: 'operation',
              part: [
                { name: 'op', valueCode: 'add' },
                { name: 'path', valueString: '/valueString' },
                {
                  name: 'value',
                  valueString: '"New updated 2"' << ,
                },
              ],
            },
          ],

overall it works , thanks for the help Rahul.
