Error on Jira form using scriptrunner to calculate a value

[mmarcus]

We have created a expense form in Jira SM in which we want to calculate the sum of a few "amount" fields. 

The script seem to be working however is not able to add the sum-value in Total Amount field.

The error is (from the scriptrunner logs)

022-06-29 02:07:31.639 WARN - PUT request to /rest/api/3/issue/PSD-1526/properties/proforma.forms.i1 returned an error code: status: 403 - Forbidden
body: {"errors":{},"errorMessages":["Property proforma.forms.i1 is restricted"],"httpStatusCode":{"present":true}}

 Any suggestions on what the issue might be?

Hi!

So, for my understanding what you're trying to do is take 2 values from a form and then edit the form, setting another field with the sum of the 2 fields?

Have a look at the Forms API documentation:

https://developer.atlassian.com/cloud/forms/rest/api-group-forms-on-issue/#api-issue-issueidorkey-form-formid-put

There is an endpoint to save form answers documented there and from the error you provided I can see a different endpoint being used.

Hope this helps!
