Error: unable to find bedrock server process

This is related to #327

I am experiencing the same issue, but my setup is different - I am running on Synology 923+ Container Manager.

```
send-command gamerule showcoordinates true
```

Error messages as follows:

```
find: '/proc/1/exe': Permission denied
find: '/proc/11/exe': Permission denied
ERROR: failed to search for bedrock server process
```

Thanks in advance!

Here are some screenshots:



Start by reading the discussion on #327 and reproducing `send-command gamerule showcoordinates true` in Synology Container Manager. Investigate the `/proc/*/exe` permission errors and the reported failure to find the Bedrock server process. Done means the command can locate the process and execute without these errors in the reported setup.
