Mail: PHP encounters a non-numeric value at /var/www/nextcloud/apps/mail/vendor/pear-pear.horde.org/Horde_Imap_Client/Horde/Imap/Client/Ids.php#317

[hansbaer443]

Expected behavior

After conecting to a new IMAP account mail-app is presenting all mails in this inbox.

Actual behavior

Mail-app shows "Keine Nachrichten in diesem Ordner" (in english "No messages in this folder") and the log shows "A non-numeric value encountered at /var/www/nextcloud/apps/mail/vendor/pear-pear.horde.org/Horde_Imap_Client/Horde/Imap/Client/Ids.php#317"

Mail app

Mail app version: 1.3.3

Mailserver or service: Icloud mail (imap.mail.me.com)

Server configuration

Operating system: Debian 10

Web server: Apache/2.4.38

Database: MariaDB

PHP version: 7.3

Nextcloud Version: 18.0.3

Operating system: Windows 8.1

[ChristophWurst]

the log shows

Mind sharing the full log entry?

[hansbaer443]

Here's the full log entry. I just removed IP address, Username und browser ID: {"reqId":"PWz0sokJNTDT0hofR4mO","level":3,"time":"2020-04-22T08:41:14+00:00","remoteAddr":"IPv6adress","user":"username","app":"PHP","method":"POST","url":"/apps/mail/api/accounts/3/folders/RHJhZnRz/sync","message":"A non-numeric value encountered at /var/www/nextcloud/apps/mail/vendor/pear-pear.horde.org/Horde_Imap_Client/Horde/Imap/Client/Ids.php#317","userAgent":"Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0","version":"18.0.3.0","id":"ID"}

Other IMAP accounts work fine. I had this issue only with a iCloud mailaccount.

[ChristophWurst]

Thanks. So it's caused by our code here: https://github.com/nextcloud/mail/blob/e5f0e3591a44a08b36c96a52eb8d9f219bb8de2c/lib/IMAP/MessageMapper.php#L152. Somehow $upper is not an int (as I would expect) and therefore the numeric operation in horde fails.

https://github.com/nextcloud/mail/blob/e5f0e3591a44a08b36c96a52eb8d9f219bb8de2c/lib/IMAP/MessageMapper.php#L134 is where we calculate it. Could you try modifying https://github.com/nextcloud/mail/blob/e5f0e3591a44a08b36c96a52eb8d9f219bb8de2c/lib/IMAP/MessageMapper.php#L110 so it casts like $max = (int) $metaResults['max'];?

[hansbaer443]

Yes, $max = (int) $metaResults['max']; fixed it!
Thank you very much for the succesfull and very fast replay!

[ChristophWurst]

Awesome. Then let me prepare a pull request :)

[ChristophWurst]

Just to be sure. Does your mailboxes show all content now as expected? :)

[hansbaer443]

Oh sorry I was too quick, I can only see 1 mail in nextcloud mail app in this IMAP account now. The no integer log entry doesn't apear anymore but i get:

Sorry for being rash

[ChristophWurst]

Oooof. Okay, I was actually afraid that could happen. Any other errors before that one?

[hansbaer443]

IMAP error reported by server

Unfortunately that is too generic to guess what went wrong.

Mailserver or service: Icloud mail (imap.mail.me.com)

How do I get an account there? :grin:

[hansbaer443]

there https://support.apple.com/de-de/HT204316

[ChristophWurst]

Okay, then I'll leave this for someone else to pick up.

@ChristophWurst I can confirm this issue. With mail version 1.4.0, it is not possible to use iCloud because of this error. If I add the cast as suggested, only 1 mail message is shown. Could the problem be related only to iCloud accounts?

[ChristophWurst]

Could the problem be related only to iCloud accounts?

Possibly, yes

That is an unrelated problem. The code fails to delete a draft message (created as you type the message). Please open a new ticket for this.
