Reproducing the Issue

Error may show in the Developer tools of the browser or when analyzing a HAR file generated by the developer tools.


Note that the error will always reference and not the customer tenant URL.

The sentry environment is an internal monitoring tool.

Any error regarding this environment does not impact the customer tenant. Do not focus on this error as a potential symptom or cause of any issue under investigation.


We are working on deploying a new Sentry environment in the coming weeks.

This issue will be automatically resolved once this new environment is deployed.

No action from Customers is required.
