Check for trailing spaces in project filenames before uploading to cloud

[raherin]

There are cases where trailing spaces that are created by mobile device keyboards by default work their way into filenames, either for photo attachments or project files when the project is created using the mobile app. This can create problems when synchronising the project because Windows will fail to download due to prohibition of files with trailing spaces. It would be good to check for trailing spaces in filenames before sync and remove them.

@raherin do you have an example of how this happened for the project files please?

[raherin]

@tomasMizera user was using the mobile app to create the project. When they put in the name for the project they left a trailing space so the project qgz file had a trailing space when the project was created.

Ah, I see

Some more information, as I was able to replicate this. The first project upload fails with dialog opening about the failure, but the project actually gets created on server. No data gets transferred besides this. The further synchronizations fail with just a notification that the project couldn't be created, so try later or contact support. The problem is that recovery from iPhone to Mac works, but recovery from iPhone to Windows doesn't.
