Could not load message.

[alam0rt]

Steps to reproduce

1. Host hydroxide (proton OSS bridge) on same host
2. Configure Mail to use Proton Bridge
3. Use it and most of the time there are time outs + general slowness. Works sometimes though

hi @alam0rt,

do you possibly have the full error trace from your nextcloud.log?

[alam0rt]

I can't find the exact trace in question, but I have found a few other interesting exceptions

    "Line": 213,
    "Previous": {
      "Exception": "Error",
      "Message": "Call to a member function getEmail() on null",
      "Code": 0,
      "Trace": [
        {
          "function": "OCA\\Mail\\Service\\Classification\\FeatureExtraction\\{closure}",
          "class": "OCA\\Mail\\Service\\Classification\\FeatureExtraction\\ImportantMessagesExtractor",
          "type": "->",
          "args": [
            "*** sensitive parameters replaced ***"
          ]
        },
        {
          "file": "/var/www/html/custom_apps/mail/lib/Service/Classification/FeatureExtraction/ImportantMessagesExtractor.php",
          "line": 55,
          "function": "array_map",
          "args": [
            {
              "__class__": "Closure"
            },
            [
              {
                "id": null,
                "__class__": "OCA\\Mail\\Db\\Message"
              },
              {
                "id": null,
                "__class__": "OCA\\Mail\\Db\\Message"
              },

the id: null items repeat hundreds of times in a single exception.

Another instance where there are many null id messages

            },
            {
              "2": {

              }
            },
            [
              {
                "id": 7,
                "__class__": "OCA\\Mail\\Db\\Mailbox"
              }
            ],
            [
              {
                "id": null,
                "__class__": "OCA\\Mail\\Db\\Message"
              },
              {
                "id": null,
                "__class__": "OCA\\Mail\\Db\\Message"
              },

# lots more of the null id messages reference 

[chookie]

I have the same issue with the same setup using Proton bridge on ubuntu 20.04. The list of mail appears in the inbox but when I click one it just stays on the spinner due to the error in the attached log.

[Joachim1305]

I have the same issue. Please see issue 4400 (nextcoud.log and horde_imap.log included).

[ChristophWurst]

# lots more of the null id messages reference 

that is actually the trace that I asked for. Please don't truncate it.

[alam0rt]

I'll include them when I have the chance. Thanks
