  @psimyn, I also noticed we have a broken error message when the errors don't load. For some reason, the "Error message:" text is at the end of the message, which doesn't make sense:

Solution

Remove the text "Error message: " suffix from the alert. Retain the existing text "Failed to load errors from Sentry".
