[GitHub] [trafficcontrol] ocket8888 opened a new issue #5103: toaccess scripts crash on connection failure
ocket8888 opened a new issue #5103:
URL: https://github.com/apache/trafficcontrol/issues/5103
## I'm submitting a ...
- bug report
## Traffic Control components affected ...
- Traffic Control Client (Python)
## Current behavior:
When a connection-level error occurs, the scripts provided by the `toaccess` package crash, printing a stack trace to stderr.
## Expected behavior:
When errors occur, scripts should print legibly what went wrong to stderr, then exit with an error code (it does exit properly with an exit code).
## Minimal reproduction of the problem with instructions:
```bash
toget -fkp --to-url "http://notarealhost.test" ping
```
## Anything else:
