Forum - 500 server error for fees

I’m getting a 500 server error when using the fees API, but only for certain users.

ExLibris Support suggested I try posting here (case 00121469)

https://api-na.hosted.exlibrisgroup.com/almaws/v1/users/90668502085/fees

{“errorsExist”:true,”errorList”:{“error”:[{“errorCode”:”INTERNAL_SERVER_ERROR”,”errorMessage”:”nThe web server encountered an unexpected condition that prevented it from fulfilling the request. If the error persists please use this unique tracking ID when reporting it: E01-0912153544-7VC1I-LIE1129451570″}]},”result”:null}

However, requesting that same user by their primary id (as opposed to the barcode) works properly.

Any thoughts on what is causing the 500 error?

Thanks
