The user activity logs show an error for an Offline Validation Rule: Unable to evaluate: ERROR: parameter for Text is nil.
Usually, the error appears because the user does not have Field Level Security (FLS) on the picklist fields in a validation rule. Users should have access to all fields referenced in Validation Rules of objects they have access to.
To prevent the error, an Admin user should do the following:
- Grant the user FLS to the specific field.
- Click the Refresh Validation Rule Data button on the Online Validation Rule Administration tab.
- Sync to download the latest Offline Validation Rule data.
