[BUG] Webklex\PHPIMAP\Exceptions\RuntimeException: idle failed

[dokicro]

Describe the bug
After 10-30minutes of running custom idle command per instructions (https://www.php-imap.com/frameworks/laravel/commands) I get the following error:

[2022-10-11 13:30:58] production.ERROR: Webklex\PHPIMAP\Exceptions\RuntimeException: idle failed in /var/www/laravel/vendor/webklex/php-imap/src/Connection/Protocols/ImapProtocol.php:1055

I am connected to Gmail business account

I played with debug mode and here is the output:

<< TAG3 OK [READ-WRITE] INBOX selected. (Success)
>> TAG4 IDLE
<< + idling
<< * 1 EXPUNGE
>> DONE
<< * 1 EXISTS
>> TAG5 IDLE
<< TAG4 OK IDLE terminated (Success)
>> DONE
<< + idling
>> TAG6 IDLE
<< TAG5 OK IDLE terminated (Success)

The problem could be that TAG5 came after TAG6 ?

@dokicro Did you get a chance to solve this?

We got a similar exception:

<< * 18 EXISTS
>> DONE
<< * 2 RECENT
>> DONE
<< TAG15 OK Idle completed (244.999 + 244.999 + 244.998 secs).
>> TAG16 IDLE
<< DONE BAD Error in IMAP command: Invalid command name (0.001 + 0.000 secs).

I did but hacky way take a look at this: Webklex/laravel-imap#453 (comment)
Everything was working fine with that workaround but then Gmail started hitting me with quota limits so I had to switch to https://github.com/dacastro4/laravel-gmail and have a corn job every minute pulling the data...

I'm using mailbox.org and I'll try out this solution: Webklex/php-imap@master...apicore-engineering:php-imap:master

In our case the problem was that after the DONE and IDLE commands the package expects the + idling or OK responses and if a new email comes in the command will fail.

Example:

>> DONE
<< * 1 RECENT
<< TAG18 OK Idle completed (0.591 + 0.590 + 0.590 secs).
