I am trying to update/insert rows using the provided R library. Trying with .netrc, explicitly setting admin user/password via labkey.setDefaults() or only using the API key generated as admin results in:

Error in handleError(response, haltOnError) :
HTTP request was unsuccessful. Status code = 403, Error message = User does not have permission to perform this operation.

Everything (API key, credentials) are tight to the administrator. I can however retrieve the data using getRows() or selectRows().

The target of the operation is a targetedmslist table that was imported via Skyline.

Any help is appreciated.

Thank you.
