Filtering Javascript errors by language

If your application has an international user base, you may be receiving Javascript error reports in the local language of your users' browsers.

While Rollbar can't translate error messages into your preferred language, it is possible to group errors by language so that you have fewer items to manage.

Here are a few custom grouping recipes to match errors based on browser language:

One supported language

The following rule groups errors where client.language.javascript does not contain en-: { "condition": { "path": "client.javascript.language","ncontains": "en-" }, "fingerprint": "non-en error", "title": "non-english error" }

Multiple supported languages

The following rule groups errors where client.language.javascript does not contain en-,fr-,de-, or es-: { "condition":{ "all":[ {"path":"client.javascript.language","ncontains":"en-"}, {"path":"client.javascript.language","ncontains":"fr-"}, {"path":"client.javascript.language","ncontains":"de-"}, {"path":"client.javascript.language","ncontains":"es-"} ] }, "fingerprint": "non-supported language error", "title": "non-supported language error" }
