Make the logging best-effort and ignore errors from GetInstanceIdentityDocument.

Can you add a log line for this error?

Thanks for the review!

The line would be logged for every invocation of the function and it would basically be a log line that says "I wanted to log something useful but the call failed so I'm logging the fact that I couldn't log something useful".

How often is this function called?

Calls to IMDS can fail for reasons other than AWS_EC2_METADATA_DISABLED, so I think its worth logging. It's only called once in an init():

cloud-provider-aws/pkg/providers/v1/aws.go

Line 473 in d7e05d5

metadata, err := newAWSSDKProvider(nil, cfg).Metadata()

we also need to update the go version to update to 1.22.7 for the govulncheck to succeed. Can you do it if possible else i can make a new PR for it?
