Permission issue?

[user9931]

When trying to open files for reading which the user under which the program is running does not have enough rights - such an error

{"level":"info","ts":1632208342.6051297,"caller":"webtail/tail.go:172","msg":"Tailer started","channel":"apt/term.log"}
{"level":"info","ts":1632208342.605446,"caller":"webtail/hub.go:302","msg":"Send reply","message":"{\"type\":\"attach\",\"channel\":\"apt/term.log\",\"data\":\"success\"}"}

        /opt/src/github-my.go/webtail/tail.go:154 +0x214

and app are closes. If we fix permissions someway the app works as it intended.
dont know if there's some useful in those lines but that problem can be easily reproduced.

@thehotery , thank you for reporting.
Ofcourse this error must be handled.
Client will receive "worker create error" If file is not readable, and tailing will be working after permission fix & page reload
