"Invalid Character" when using Scope names with state

When using the AspNetCore ILogger like this:

using (logger.BeginScope("HTTP {HttpMethod} {Uri}", "123", "1234")){
	logger.LogCritical("Test");
}

This creates a scope called “HTTP 123 1234” and additional tags “HttpMethod: 123” and “Uri: 1234”. Sentry successfully gets the tags but the scope results in an error in the sentry frontend like this:

The tags json will contain:

{"value":"HTTP {HttpMethod} {Uri}","key":null}

I think Sentry should be able to use “HTTP 123 1234” as value and probably have “scope” as a tag key (Are arrays supported as tag keys?)

Sounds like we’d need to special case for that, and extract the key from the message format (like {a} would be key a) to add the tags.

That actually already works. With the example above I get “HttpMethod” as Key and “123” as value but the message itself is passed without any kind of replacement and any kind of key which marks it as invalid in the frontend. I guess the tags work cause FormattedLogValues is based on a IReadOnlyList<KeyValuePair<string, object>>

I can take a look if I can get a PR ready 😄

I am experiencing this exact problem too. We have recently updated our asp .net core version to 3.1 and sentry to 2.1.8
