awsemf not handling httpstatus.check from httpcheckreceiver correctly

What happened?

Description

I'm trying to get synthetic healthchecks as metrics in CloudWatch with the configuration in my attachment. The issue is that awsemf doesn't seem to take the correct datapoint value:

When http.status_class is 2xx and the http.status_code is 200, the datapoint value should be 1, which is correct when I output it with the debug exporter:

Debug output looks like this:

Data point attributes:
     -> http.url: Str(http://www.github.com)
     -> http.status_code: Int(200)
     -> http.method: Str(GET)
     -> http.status_class: Str(2xx)
StartTimestamp: 2025-06-25 12:27:53.257405985 +0000 UTC
Timestamp: 2025-06-25 12:27:54.260995723 +0000 UTC
Value: 1

Now if I look at the stdout of the awsemf, I see that the same datapoint is declared as 0 even though http.status_class is 2xx and http.status_code is 200:

OTelLib=github.com/open-telemetry/opentelemetry-collector-contrib/receiver/httpcheckreceiver Version=1 _aws={"CloudWatchMetrics":[{"Namespace":"app_httpcheck","Dimensions":[["http.method","http.status_class","OTelLib","http.url","http.status_code"]],"Metrics":[{"Name":"httpcheck.status","Unit":"","StorageResolution":60}]}],"Timestamp":1750854998791} http.method=GET http.status_class=2xx http.status_code=200 http.url=http://www.github.com httpcheck.status=0

Steps to Reproduce

I've added a working config as attachment.

Expected Result

• awsemf interprets the datapoint according to the input of the httpcheck receiver
