Add Inbound Filters in Sentry

Choose the project where the error is coming from.

Click the settings icon in the top right.

Click "Inbound Filters"

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.

To save, click outside the field and you'll see this confirmation message.
