Error with CakePHP: Uncaught RuntimeException: You cannot call all() on a non-select query. Use execute() instead.

I'm using the latest rollbar version (2.0.0). Rollbar has started throwing this exception recently. I could not find the relevant method from the stack trace.

Looks like Rollbar is trying the serialize the Query object involved in the exception (to include in the payload) and fails.

Start in vendor/rollbar/rollbar/src/Utilities.php at the serialization paths shown in the stack trace, especially lines 102 and 159, and reproduce the failure with a Cake\ORM\Query non-select query. Done means serializing the query for the Rollbar payload no longer raises the CakePHP all() exception; no test file is named in the issue.
