Incompatible Data, try updating the app

[dcowan-london]

When I try to launch the Store, I get a banner at the top of the screen saying "Incompatible Data, try updating the app". This also appears in the WebIDE console.

hello :)
Same exact issue here on a new Nokia 2720 Flip :)
a couple of reboot didn't do much sadly

same issues, no matter : reboots/reinstalls

Hey,
The reason this error is appearing is because the application is expecting the store version (from the server - https://banana-hackers.gitlab.io/store-db/data.json) to be 2 (

bHacker-store-client/application/assets/js/backend_api.js

Line 50 in 97a4160

if (json.version !== 2) {

) - and it seems to be 3.

Also, second mirror (

bHacker-store-client/application/assets/js/backend_api.js

Line 6 in 97a4160

"https://bananahackers.github.io/store-db/data.json",

) is very broken - last actual commit was 30 October 2020 (bananahackers/bananahackers.github.io@296fa35)

good points mate.

So here's what I've found:

After changing the 2 to a 3 (

bHacker-store-client/application/assets/js/backend_api.js

Line 50 in 97a4160

if (json.version !== 2) {

), at first, everything seems to work.

When I try installing an app, however, it just sits there with a loading bar at the top forever. Nothing appears in the WebIDE console.

The issue seems to be that navigator.mozApps.mgmt.import() (which the store uses to install the package -

bHacker-store-client/application/assets/js/install.js

Line 87 in 97a4160

.import(packageFile)

) doesn't exist (TypeError: navigator.mozApps.mgmt.import is not a function), but still, for some reason, doesn't fail the error check (

bHacker-store-client/application/assets/js/install.js

Line 65 in 97a4160

if (!navigator.mozApps.mgmt.import()) {

) - it just aborts at that point.

I tried enabling the experimental alternative installation method (

bHacker-store-client/application/assets/js/install.js

Line 73 in 97a4160

let req_install = window.navigator.mozApps.install(packageFile);

). The error I got back was:

{"isTrusted":true}

I've never done anything like this before, and there's very little documentation for any of this online (all the Mozilla documentation for FirefoxOS has been taken down, and from the archives I can find, there seem to have been changes made to KaiOS, so it's not quite compatible), so there's not much else I would know to try.

What I think is most likely, is that a recent update to KaiOS broke the installation method the store was relying on.

It is possible that it might work on other KaiOS phones - all this was done on a Nokia 8000 4G.

Update: I've just tried it in the KaiOS emulator (stock, with just the store version changed), and got this error -

bHacker-store-client/application/assets/js/install.js

Line 108 in 97a4160

"Installation error: You probably need to do the priviliged factory reset first."
