The same errors for my Javascript application are repeatedly sent to the rollbar. Is there a way to prevent the same errors from being sent after a certain limit?
Probably your best option here is to mute that particular error.
Muted items represent issues that are not currently worth investigating. In the Muted state:
If you have an item that you consider a non-issue, or otherwise don't plan to do anything about soon, you can Mute it so it stays out of sight.
Muted items are still indexed, searchable, etc. and can be changed back to Active at any time. For this reason, occurrences of Muted items do count for billing purposes. If you need to reduce your usage, you should set a rate limit or filter it before it is sent to Rollbar.
