Inconsistent behaviour regarding forwardErrorsToLogs and forwardConsoleLogs

[OliverJAsh]

When forwardErrorsToLogs is explicitly enabled, Datadog adds error to forwardConsoleLogs:

browser-sdk/packages/logs/src/domain/configuration.ts

Lines 85 to 87 in 8df6ac0

	if (initConfiguration.forwardErrorsToLogs && !forwardConsoleLogs.includes(ConsoleApiName.error)) {
	forwardConsoleLogs.push(ConsoleApiName.error)
	}

However, if forwardErrorsToLogs is omitted from the initial configuration, this does not happen, despite the fact that forwardErrorsToLogs defaults to true.

Datadog should behave the same when forwardErrorsToLogs: true and when forwardErrorsToLogs is omitted.

On a related note, I find it strange that you can't opt out from console.error collection when forwardErrorsToLogs is specified, even when specifying forwardConsoleLogs: [].

(When specifying forwardErrorsToLogs: true, forwardConsoleLogs: [], Datadog will resolve the configuration as forwardConsoleLogs: ['error'].)

Ooh thank you for pointing that out, we'll fix this.

I agree that it can be a bit confusing. To understand why it works like this: at first we had forwardErrorsToLogs but not forwardConsoleLogs. At this time, when setting forwardErrorsToLogs: true, we considered console.error to be errors, and forwarded it as such. When we introduced forwardConsoleLogs, we didn't want to change the forwardErrorsToLogs behavior, this is why we enforce forwarding error logs in this case. I hope it makes sense.

Thank you for the feedback, we might consider clarifying things in a future major version.

It seems to be a breaking change: users using the default configuration would start collecting console.error without opting in. I added this to the list to do for our next major.
