What happened to the field LopMostSpecificTargetId?

[Johnny]

hi,

Looking at the docs in https://developers.google.com/adwords/api/docs/appendix/reports/click-performance-report it appears there's a field called 

LopMostSpecificTargetId, but when I query for it I get:

HTTP code: 400, error type: 'ReportDefinitionError.INVALID_FIELD_NAME_FOR_REPORT', trigger: '', field path: 'LopMostSpecificTargetId'





What's the problem?

Hi Johnny,

The field LopMostSpecificTargetId was recently added to v201509. If you are using an earlier version of the API, you will run into this error. 

Please follow our migration guide for v201509.
