N1QL error. Usually out of memory

Error: An unknown N1QL error occured. This is usually related to an out-of-memory condition. Check the errors responseBody property or inspect the cluster logs for further details.

doctor sdk Summary:
[WARN] Your connection string specifies only a single host. You should consider adding additional static nodes from your cluster to this list to improve your applications fault-tolerance
[WARN] Bootstrap host xxxxxxxxxxxx is not using the canonical node hostname of xxxxxxx.ap-south-1.compute.amazonaws.com. This is not neccessarily an error, but has been known to result in strange and difficult-to-diagnose errors in the future when routing gets changed.
[WARN] Memcached service on xxxxxxx.ap-south-1.compute.amazonaws.com:11210 took longer than 10ms (was: 83ms) on average to reply. This is usually due to network-related issues, and could significantly affect application performance.
[WARN] Memcached service on xxxxxxxxxxxx.ap-south-1.compute.amazonaws.com:11210 took longer than 20ms (was: 350ms) to reply. This is usually due to network-related issues, and could significantly affect application performance.

This is straight forward there might be some setup issue . Why do you use back-ticks in fromString.
Check 8093 port is open

I would recommend two quick things.

First, just to validate the setup, try running SDK doctor.. It will validate the setup between the place you’re running the client and the cluster. You’ll find pre-built binaries on the release page.

Usually the summary at the end is pretty easy to interpret. If you need help with interpretation, please feel free to post it or a link to it here.

If that is clean, then I’d recommend turning up the log level and looking at the output.

Summary:
[WARN] Your connection string specifies only a single host. You should consider adding additional static nodes from your cluster to this list to improve your applications fault-tolerance
[WARN] Bootstrap host xxxxxxxxxxxx is not using the canonical node hostname of xxxxxxx.ap-south-1.compute.amazonaws.com. This is not neccessarily an error, but has been known to result in strange and difficult-to-diagnose errors in the future when routing gets changed.
[WARN] Memcached service on xxxxxxx.ap-south-1.compute.amazonaws.com:11210 took longer than 10ms (was: 83ms) on average to reply. This is usually due to network-related issues, and could significantly affect application performance.
[WARN] Memcached service on xxxxxxxxxxxx.ap-south-1.compute.amazonaws.com:11210 took longer than 20ms (was: 350ms) to reply. This is usually due to network-related issues, and could significantly affect application performance.

Yeah, that’s pretty clear. It looks like you must be running the client across a congested network or a wide area network or both. We test and technically only support the client/cluster on a LAN like network. The memcached service is typically around a millisecond.

Can you run the client near the cluster?
