Justin Toth added a comment - 21/Apr/2018 1:48 PM @Gregory Joseph, this ticket needs to be reopened. To say that the api doesn't work this way, but not provide a solution for the customer's use case isn't an acceptable resolution. We're constantly getting this error (Please provide a valid value for field 'Raise this request on behalf of') when users submit support tickets who have submitted ones in the past, as they are now considered "existing users" in Jira. These support tickets are generated via our contact form on our website and mobile apps, so all they provide is an email address, we don't have any sort of "username" for them since many are anonymous users who haven't even created an account with us yet. Jira has the capability to solve this problem (your database stores the user accounts and their email addresses so can map the email address to an existing user), we do not have the capability to solve this problem (we don't know the user account for an email address), so you need to give us a solution. Here is the code for submitting a support ticket to jira: https://gist.github.com/justintoth/cf0eb315f7e60ee6a4c903df10498175 And here is the error: error: {"errorMessage":"Your request could not be created. Please check the fields have been correctly filled in. Please provide a valid value for field 'Raise this request on behalf of'","i18nErrorMessage": {"i18nKey":"sd.validation.request.creation.failure.required.field","parameters":["Please provide a valid value for field 'Raise this request on behalf of'"]}
