If your Zap is returning an Errored status of "undefined method `connected?' for nil:NilClass", there may be an expired connection.

To fix this, go to your Zap and click Edit Zap.

On the right you will see a "Please connect this account", click it to go to the step in the settings where you can re-connect to TrueReview.

Once fixed, click Publish Zap and go to your Zap History. Under Zap Runs, select Stopped/Errored.

Select the Zaps that had an error and click Replay. This will run the zap again.
