Crash on Upload of empty files

[charlesangus]

Uploading from a simple project crashes the app. Restarting Input and trying to upload again results in a popup saying, "Another process is running. Please try again later."

Project has two editable layers, a point layer and a line layer. The point layer has photos attached.

A simpler project with just an editable point layer uploads fine.

What platform is it - Android or iOS ? Could you please share the project folder you are trying to sync? Also, there is a hidden file in INPUT/projects/.logs - it would be useful if you could send it as well - there may be some valuable information from the previous failed sync. If your data are private, feel free to send them to me at martin.dobias@lutraconsulting.co.uk

Regarding "Another process is running" message - that happens when server thinks there is a pending upload - here it's before the upload crashed. The project will get unlocked in 5 minutes and it should be possible to sync again.

This is Android 10. I have sent the project folder and the .logs file to the email specified. Thanks!

Thanks for the project folder + logs file. I can confirm a crash on sync which prevents uploads of any changes. The reason is that there are empty files which Input wants to push, but crashes before doing that:

#6  0x00005555555bf0b5 in MerginApi::uploadFileReplyFinished() (this=0x555555b576d0) at ../app/merginapi.cpp:1514

In MerginApi::uploadFile() we try to get the first chunk, but file.chunks is actually an empty list which causes the crash.
