I am trying to run the couchbase exporter(latest version) in docker to get the couchbase metrics in to Prometheus but the container is crashing with the below error logs.

[signal SIGSEGV: segmentation violation code=0x1 addr=0x30 pc=0x7b4979]
The exporter is connecting to couchbase DB but not able to get the metrics due to this error
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x30 pc=0x7b4979]
Here are the links to Couchbase exporter code and the image registry.

I am suspecting that the exporter code is having a bug but I am new to couchbase and GO, so looking for the help here.
Has anyone successfully used the latest version of couchbase exporter (container based) to get the couchbase metrics?
