In the following example the JSON array contains workerinformation only if the account is linked to an identity. Service accounts do not have workerinformation. This results in an uneven JSON array where the service accounts have less array elements than the identity accounts. Note that identity account cblossom has workerinformation and service accounts fa_operator and fa_guest do not have workerinformation.

The JSON parsing looks like this:
Note that if the personNumber Collector Mapping Parameter is removed, the error does not occur.
Cause
This error is caused by parsing a Collector Mapping Parameter that is not part of every array element in the JSON array. In the above example, personNumber is part of workerinformation which is not part of every array element. Removing this parameter, leaves only fields AccountID and isActive which belong to all array elements and do not cause the error.
Resolution
