Bug reporting - stack level too deep ec2_metadata.rb #49

Open azman0101 opened 4 years ago

azman0101 commented 4 years ago

With this configuration:


    <match **>
      @type ec2_metadata

      # aws_key_id  YOUR_AWS_KEY_ID
      # aws_sec_key YOUR_AWS_SECRET/KEY

      metadata_refresh_seconds 300 # Optional, default 300 seconds
      imdsv2 false                  # Optional, default false

      output_tag ${availability_zone}.${tag}
    </match>

I get this error:
