Hi @jungalwala,

Thank you for taking the time to report this. We are going to investigate it and will update this topic as soon as we have more information.

Thanks

Hi @jungalwala

We could reproduce the issue and found that the configuration file is wrong. For example, the url to check is now

 <URL "http://localhost:5984/_node/_local/_stats">

as you can see in the server's documentation.

https://docs.couchdb.org/en/2.3.1/api/server/common.html#node-node-name-stats

However, if you change that, the error in the log file still persists. The team will continue checking it.

Thanks

Hi @jungalwala,

It seems you need to configure the credentials for the stackdriver agent. Sometimes the default configuration works on GCP but other times not. You can refer to this page to configure the crendentials.
