Navigate to https://sentry.io/ and go to the projects page.

Choose the project where the error is coming from.

Click the settings icon in the top right.

Click the "Error Message" field and add the error. Different errors can be placed on different lines. You can use a * symbol as a wildcard. For example *No host permissions for cookies* will get everything where that string is in the middle of the error.
