IgnoreErrors not filtering certain events.

[rodolfoBee]

Trying to filter the following errors on the SDK side:

*mysql.MySQLError
Error 188 (HY000): FTS query exceeds result cache limit

For that, we are using the ignoreErrors configuration with value: Error 188 (HY000): FTS query exceeds result cache limit, however it does not filter the events. Changing the filter to only FTS query exceeds result cache limit serves as a workaround.

opts := sentry.ClientOptions{
    Dsn: config.Sentry.Dsn,
    Debug: true,
    Integrations: func(i []sentry.Integration) []sentry.Integration {
            return i
    },
    IgnoreErrors: []string{
            "FTS query exceeds result cache limit",
    },
}

SDK version: 0.25.0.

Since the values in IgnoreErrors are converted to regex patterns, characters ( and ) need to be escaped for this to work.

This is how you can add it:

IgnoreErrors: []string{`Error 188 \(HY000\): FTS query exceeds result cache limit`},

Could we change IgnoreErrors to take both regex and strings into account? Same for IgnoreTransactions.

That's definitely a possibility. Is it handled that way in other SDKs?

Yep, e.g. in JS https://docs.sentry.io/platforms/javascript/configuration/options/#ignore-errors
