Cannot resume stream because SMID was previously deleted (`no_previous_session_for_smid` | XEP-0198)

MongooseIM version: 6.2.1 Installed from: image Erlang/OTP version: 26

Hey 👋🏻

I'm trying to implement stream resumption, and even though it works most of the time, there are cases where I receive this element:

<failed xmlns='urn:xmpp:sm:3'>
  <item-not-found xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
</failed>

This is because MongooseIM cannot find the SMID, but it's not clear the reason.

Example in the logs:

Not sure if I'm missing something here. Any help will be appreciated! Thanks. 🙏🏻

Hi, We've recently expanded our tests to cover the usage of mod_stream_management using the WebSockets API. During this process, we identified and fixed some errors and bugs. These changes were included in a recent pull request (https://github.com/esl/MongooseIM/pull/4303) that has already been merged into the master branch. Could you please check if the error is still present in the current master version?

[hpedrorodrigues]

Sure! I'll check the master branch, then. I'll let you know my findings!

[JanuszJakubiec]

Hi, have you experienced any issues with stream resumption using WebSockets after the version update? If everything is working fine, I'll proceed with closing the issue.

[hpedrorodrigues]

Hi. Yes, I'm still experiencing this issue. I'll collect a few things and will comment here soon.
