Error Log entrys

[KoMa1012]

Steps to reproduce

1. no trigger point found, just happens

Expected behavior

no entry in error log

I don't know if it is related, but I'm seeing issues with drafts, it stores multiple drafts if I create an e-mail, it seems like it's not recognizing old drafts.

Actual behavior

Multiple entries in error log, I'm not sure how they relate to each other, but they show up indipendendly.

Auth and Rubix are unrelated

Rubix probably shows because you just updated the app. Check again tomorrow when all ML models have been regenerated with the new version of the Rubix lib.

[KoMa1012]

rubix is appearing every ~2-3times per day since a while now, not only since the update.

[ChristophWurst]

:eyes: @st3iny

[st3iny]

Something weird is going on here. Did you downgrade the Mail app recently?

The stable2.2 branch is still on the old persistence code and should not throw those errors.

[KoMa1012]

no, I never downgraded, I only went up in versions.

[ChristophWurst]

Navigate to your Nextcloud root directory and search for the Encoding.php class like

$ find . -path "*/src/Encoding.php"
./apps/mail/vendor/rubix/ml/src/Encoding.php
./apps/suspicious_login/vendor/rubix/ml/src/Encoding.php

[KoMa1012]

find . -path "*/src/Encoding.php" returns: ./apps/suspicious_login/vendor/rubix/ml/src/Encoding.php

[KoMa1012]

is there any more information required by me? Because it is still labeled as "needs info"

[st3iny]

No, all good. Thank your for helping with debugging.

We had a suspicion which you confirmed. The suspicious_login app is shipping a newer version of Rubix which is overriding the version of the mail app. That is problematic because there are incompatibilities between the two versions which break classification if both apps are used together.

We will work on a solution when time permits. Please be patient or disable the suspicious_login login app in the meantime.

[KoMa1012]

suspicious_login app is and was deactivated, it's still howing up in the app list (there is no remove button). If you don't remove the data manually your explanation doesn't fit my experience.

[st3iny]

Right, the app is shipped and can't be removed. I forgot about that, sorry :sweat_smile:

In that case, I fear we have to work on a solution with a bit more urgency.

[marianionut]

This is happening to me also, I have ubuntu 22.04 and nextcloud snap version 25.0.6

I disabled the suspicious_login app, but I'm still seeing

Errormail2023-04-28T20:20:10+0300
OCA\Mail\Exception\ServiceException: Deserialized estimator has an unknown type Rubix\ML\Encoding

[vitis586]

Personally I had to delete suspicious login folder from my Nextcloud apps folder.

[KoMa1012]

still active in mail 2.2.6 with NC 25.0.7.
