OwnTracks 17.0.3 immediately crashes and closes on non-json payloads

[ArjanM83]

Since upgrading to iOS 17.2, when opening OwnTracks, it immediately crashes and closes. Also, it does not send out reports.

• OwnTracks version 17.0.3
• Using HTTP

[jpmens]

Which release of OwnTracks are you using, and in which mode (MQTT or HTTP)?

Sorry forgot to add details:

• OwnTracks version 17.0.3
• Using HTTP

I have a device with 17.0.3 and upgraded to iOS 17.2 without problems. With previous iOS updates we saw problems on a few devices which could be solved by restarting the phone...

I tried restarting. But still when opening OwnTracks, it closes again in 1-2 seconds. I can't reach the settings in time to change anything.

Would you put the iPhone in Flight mode and try again? If it works then, the problem is related to the backend connection. What kind of backend do you use? recorder?

Thank you for the suggestion. In Flight mode OwnTracks does not close.

My backend connection is a custom HTTPS server that hasn't changed in years.

Now you can use the new log feature: On the status screen, select log, then select the most recent logfile and export it. Have a look, or send it to us (support@owntracks.org)

Sounds good. I will check it tonight.

I'm seeing the same behavior (crashing immediately upon opening the app, and it not sending updates) but I'm still running iOS 17.1.2. I am on the latest Owntracks (17.0.3) and using a custom HTTP server that hasn't changed in long time.

Between App Store auto updates and not leaving the house I can't pinpoint it but would guess it was introduced in the latest Owntracks update.

It still crashes after a reboot. It does not crash in airplane mode with WiFi turned off.

[jpmens]

Could you please show us an example of the data being returned from your custom HTTP server to OwnTracks on iOS? You are welcome to redact the values of course but please DO NOT modify any quotation marks.

In case of doubt, gladly send the data to support@owntracks.org for us to look at.

[jpmens]

@CharlieParcer we’d also appreciate if you could please

1. enable flight mode so OwnTracks can’t contact your server
2. open the app and where the settings are you should see a “Logs” menu.
3. select the last two or three logs and mail them to yourself or directly to us at the above email; during the emailing you’ll need to disable flight mode of course :-)

I restarted my HTTPS-server to be sure there is no problem on that side, but it's working fine with other HTTPS-services.

While in Flight mode, I extracted the last log from the log screen in OwnTracks, removed my credentials and Wi-Fi SSID and emailed it to support@owntracks.org

Let me know if you need any more testing, but I won't be able to reply until tomorrow morning.

Problem is now clear: It is not related to iOS 17.2, but just to the new OwnTracks app version 17.0.3 It crashes if a non-json payload is sent by the backend. This happens in HTTP or MQTT mode. Returning e.g. an empty json {} avoids the problem when in HTTP mode. Will provide a new version, but this will take a day or two until it hits the App Store.

[jpmens]

@ArjanM83 thank you for the data you provided!

[ckrey]

A new version 17.0.4 is available in the app store now. Sodrry again for the inconvenience anf thanks for reporting

[yantoz]

I still get crashes with 17.0.4 on similar JSON issue. I got this in the log:

2023-12-15T14:37:58.693Z  Validation error: Error Domain=com.argentumko.JSONSchemaValidationError Code=300 "JSON instance validation against the schema failed." UserInfo={path=, object={
  "_type" : "lwt",
  "tst" : 1702479180
}, NSLocalizedDescription=JSON instance validation against the schema failed., validator=<DSJSONSchemaObjectValidator: 0x2820b7260>{ maximum properties: none, minimum properties: 0, required properties: _type, data }, NSLocalizedFailureReason=Object is missing required properties: 'data'.} with {"_type":"lwt","tst":1702479180}

I am using websockets/https protocol. The app connected to the mqtt server and sent lwt message before crashed.

[jpmens]

@yantoz that's a validation failure which shouldn't be the cause of the crash.

Please send us (support@owntracks.org) the last two logs, available from the (I) screen. If need be switch to flight mode to enter the app.

[ckrey]

you are probably using application level encryption. Will have to look. lwt message is not and never was encrypted

[nlanfran]

It is still crashing with iOS 17.2 and 17.0.4 using MQTT. The app is fine until I insert the MQTT host address, then it crashes and not being able to open it since (opens and immediately closes).

[jpmens]

Have you tried putting the device in flight mode until you enter a valid configuration?

[yantoz]

@yantoz that's a validation failure which shouldn't be the cause of the crash.

Please send us (support@owntracks.org) the last two logs, available from the (I) screen. If need be switch to flight mode to enter the app.

ok, just sent the log. I have only one log file.

The same issue for me, app crashes immediately after opening,which started few days ago:

• iOS 16.7.X and 17.2(upgraded yesterday)
• App 17.0.3 and 17.0.4
• Server connection: MQTT with TLS and no change on server side in the last months If needed, I may provide the log file.

[yellowonblack]

The same error in the logs like @yantoz already provided:

2023-12-16T07:43:54.829Z Validation error: Error Domain=com.argentumko.JSONSchemaValidationError Code=300 "JSON instance validation against the schema failed." UserInfo={path=, object={ "_type" : "lwt", "tst" : 1702568586 }, NSLocalizedDescription=JSON instance validation against the schema failed., validator=<DSJSONSchemaObjectValidator: 0x283e6b580>{ maximum properties: none, minimum properties: 0, required properties: _type, data }, NSLocalizedFailureReason=Object is missing required properties: 'data'.} with {"_type":"lwt","tst":1702568586}

[nlanfran]

I just sent the log file to support@owntracks.org

[ckrey]

Thanks @nlanfran your log was very helpful. I found the problem caused by mixing encrypted and unencrypted messages, which are not handled correctly since version 17.0.3

[ckrey]

@yantoz thanks for providing the log. The problem is now solved and will be available shortly as version 17.0.5 in the app store

[yantoz]

@yantoz thanks for providing the log. The problem is now solved and will be available shortly as version 17.0.5 in the app store

@ckrey I confirmed that 17.0.5 solves this issue. No crashes anymore. Thanks!

[ckrey]

Happy to hear that

[yellowonblack]

Problem solved in 17.0.5. Thanks @ckrey.
