Jarvis translates field names to match the format you used for your submission. So if there's an issue with a worker's date of birth, the error message will refer to:
Format | Field name shown |
PAPDIS | BirthDate |
NOW:Pensions | DOB |
NEST | Date Of Birth |
JSON / API | birthDate |
This should make it easier to find the relevant field in your data. If you're not sure which field is being referenced, get in touch and we'll help.
