Trips not recorded on iOS

[MythriNagaraju]

@shankari : After I merged changes to update the sdk to 26 and switch dynamic permissions, the iOS app is not recording trips at all. I also do not see any errors in the XCode log. Is anyone else running into this issue?

[shankari]

@MythriNagaraju none of the changes to update the SDK to 26 applied to iOS, so I have not tested or released a new iOS version. I can't think of any obvious reasons why the plugin updates (the only changes to iOS) should have broken tracking, but you might want to try syncing to tag 2.7.1 (https://github.com/e-mission/e-mission-phone/releases/tag/v2.7.1) and rebuilding on iOS.

That is the version currently in the stores and being tested by users. If that also does not work for you, let me know and I can help you troubleshoot.

[MythriNagaraju]

Thanks @shankari , I'll try doing that. I am using cordova version 8.0.0. Could that be a problem?

[shankari]

@MythriNagaraju I don't think so - the README recommends using cordova 8.0.0 since Jan 2018
https://github.com/e-mission/e-mission-phone/blame/master/README.md#L159
so that is what I must have used to build the working version in the stores.

Okay, this time I double checked that the location tracking button was on and both iOS and android apps are recording trips. Although nothing is being logged on the server. I emailed you the log. Would you be able to take a look please? Thanks!

[shankari]

@MythriNagaraju I checked your logs and there was an network error while connecting to the server.

@MythriNagaraju You can check the logs yourself and confirm. There is documentation on how to make the emailed database human readable in

https://github.com/e-mission/e-mission-docs/blob/master/docs/e-mission-phone/troubleshooting_tips_faq.md#reading-the-log-on-your-computer

You can also browse logs using the Profile -> Developer Zone -> Check Log

Thank you - I am looking at the .csv file now. I was connected to the server when I force-synced. And force-sync worked from the android app at the same time.

[shankari]

But was your iPhone connected to WiFi or a data plan?

[MythriNagaraju]

Yes!

[shankari]

were you able to access the server (https://....) from safari on the iPhone?

[MythriNagaraju]

Yes, I was able to.

Also, I see this error in the logs while trying to push data to the server:

Error Domain=com.google.HTTPStatus Code=413 ""(null)""

Have you seen this before?

[shankari]

hm, status code 413 is "Payload Too Large"
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/413

That is basically a dup of #283
They were using e-mission behind a reverse proxy, and hadn't bumped up the max request size on the proxy to match the size in e-mission.

They submitted a doc fix (#47) I requested changes, but haven't received a response yet. But you can use the doc fix directly :)

[shankari]

I am not quite sure about why you should be hitting this though. The previous team that ran into this was returning survey results, and our speculation was that the survey result sizes were big. But you are not using surveys. Let me take a closer look.

[shankari]

But you should definitely bump up the max size in the short-term because I know that will fix it.

[MythriNagaraju]

I did bump up the max size in cfc_webapp.py , but that will not work because the server is behind a reverse proxy. I cannot use that doc fix though because in my case the web server is on a windows server and behind a IIS webserver proxy.
