Hello,  
I’m using binary go lang plugins, these plugins are sending huge run time stack trace to pagerduty and to slack. like below:  
version: sensuctl version 5.21.5+oss\_el7+ce, community edition, built 2021-05-11, built with go1.15.5

Can we restrict this behaviour and configure such that it should not send runtime stack and only send brief error?

node-name : fatal error: runtime: out of memory  
runtime stack:  
runtime.throw(0x55cdaf, 0x16)  
/opt/go/src/runtime/panic.go:608 +0x72 fp=0x7ffefe9bd1b0 sp=0x7ffefe9bd180 pc=0x429722

Kindly please help!

It looks like your CLI is a pretty old version. Sensu Go 5.21 was released in June 2020. What version is your `sensu-backend`?

If you can access the Sensu Backend node, you can run the command:

```auto
$ sensu-backend version 

```

The latest version backend looks like this:

```auto
6.5.4+ee, enterprise edition, build 17bff5d44e20571df95270d1a81367dc064bc097, built 2021-10-30T21:54:05Z, built with go1.17.1

```
