This error means Salesforce couldn't run the query behind a Data Wizard job built on a SOQL query, List View, or Campaign. Ensure that the user has adequate access.

There are a few common causes:

• Invalid SOQL syntax: the query saved on the wizard no longer runs as written.
• A field or object was renamed or deleted: the wizard was saved against an object or field path that's since changed in Setup, so the saved query can no longer resolve.
• A field isn't queryable, or the running user lacks access to it: field level security or object permissions are blocking a field the query depends on.

Note: Validation runs as whoever is viewing the wizard at the time, but scheduled or manual runs execute as the wizard's designated Run As user. If that user has different field or object access, the same query can fail here even though it passed validation.

To resolve it, check the source of the Data Wizard or SOQL query. Confirm the object/fields it uses still exist, and confirm the Run As user has access to everything the query touches.
