"The getter 'isNotEmpty' was called in null"

[manwithpowers]

Hi,

First, thanks for the great web app and for this new mobile app.
I installed the tester/developer version from Google Play, and am receiving the following error in the app:
The getter 'isNotEmpty' was called in null.

I am running a self-hosted installation and the latest version of the web app (4.5.0).

Thanks for trying out the app!

Another user reported the same error. I'm not seeing it which make me think it's related to specific data not being set. I hope to have a fix in the next release.

Great, thanks! Happy to help if you need specifics on my install, etc.

I'm seeing this as well, but only on some pages.

On the clients page it shows after a couple of clients.
On the invoices page, it shows in the whole of the content area.

The dashboard displays fine.
Products page seems to be fine (I only have 3 products in the system).

On the invoices screen I can get a partial fix by changing the sort order.

Rather than filling the whole screen, the errors only start at a certain point.

If I compare to the listings in the webapp then it seems to break on a client that has an umlaut in the name Gästehaus.

It looks to be similar for the other screens that can be sorted.

This should be fixed in the next version of the mobile app.

• Which versions of the web and mobile app are you using?
• Which screen do you see the error on?

Firestore.instance.collection("postman").getDocuments().then((querySnapshot) {
querySnapshot.documents.forEach((result) {
if(querySnapshot.documents == null) return CircularProgressIndicator();
print(result.data);
var link = result['link_data'];
var share = result['share_app'];
var youtube = result['youtube_link'];
assert(share is String);
assert(link is String);
assert(youtube is String);
MovieListDemoState.text = share;
MovieListDemoState.youtubelink = youtube;
Services.postmanurl = link;
return Services.postmanurl = link;
});
});

this is my code

@Sreejith93 If the error you're seeing isn't from the Invoice Ninja app then posting here for help is inappropriate
