How to populate customer user picker field with component lead

[James_Noble]

I am being asked to populate a custom field with the component lead value.

This is so we can have the accountable component lead value, displayed on any given screen.

I have tried with REST API to do this using automation but have failed unfortunately, even using Copilot to help.

This is the error I get in the automation flow audit log

Error found in the HTTP body response:

{"errorMessage": "Site temporarily unavailable", "errorCode": "OTHER"}

Any help gratefully received.

Hello @James_Noble ,

do you have more details about the automation steps?

E.g. the url and header used for the api call

Best regards

Hi

thanks for coming back to me 

... atlassian.net/rest/api/3/component/10174 when I hard code the end value and 

atlassian.net/rest/api/3/component/{{issue.components.first.id}} when I use the 

However using the hard coded value brings back a different ID in the audit log for the failure.  I raised an Atlassian support ticket also, in case this is a platform error.

 Unable to publish the web request - received HTTP status response:

404

Error found in the HTTP body response:

{"errorMessages":["The component with id 10104 does not exist."],"errors":{}}

 Happy to get schooled on this in any way necessary... :)
