I'm trying to use the XML content negotiation, but it just fails without it making sense. I'm getting this error, and the firstname field does exist.
Could not find a field for name Attendee/FirstName
candidates: firstname, middleInitial, lastname, suffix, title, company, externalId, custom1, custom2, custom3, custom4, custom5, custom6, custom7, custom8, custom9, custom10, custom11, custom12, custom13, custom14, custom15, custom16, custom17, custom18, custom19, custom20, custom21, custom22, custom23, custom24, custom25 at position Line number = 3
I have tried renaming the
firstname
to
FirstName
, but it still won't find it and just give the same error.
