Cannot read mkdirs of null

[kryptus36]

I'm not sure if this issue is in core, ui-lottie or I'm missing something?

I've made sure my file is in the right place.

Error is on line 387 of the first file in the stack trace. So it's throwing from core file-system on android.

The line is : javaFile.getParentFile().mkdirs(); - so the parent file is returning null causing the issue. Not sure why. Seems like a file is missing.

[kryptus36]

Right, and the filename in question is a json file, which exists in App_Resources/Android/src/main/assets so I'm a little confused.

[farfromrefug]

What s the src value ?

[kryptus36]

src="1801-fireworks.json"

The loaded function just has a console.log call in it (and never fires, obviously)

I'm running the latest nativescript available

[farfromrefug]

@kryptus36 you did not set any path to the file. It simply cant find it. You need to add the path tothe file

[kryptus36]

I'm misunderstanding then. From the examples and demo code I thought the path was relative to App_Resources/Android/src/main/assets

What should the path be?

[farfromrefug]

@kryptus36 depends on where you put it. It works like any resource handling in . like image https://v7.docs.nativescript.org/ui/components/image

[kryptus36]

When I download LottieLogo1.json from the sample dir on this project and put it in app/assets/lotttie/LottieLogo1.json Then set

`

`

I get

Unable to parse composition

[farfromrefug]

Much better now please share your package.json.

Thanks for your time on this.

Ok that wont help.as you are using ^. Because of that i dont know which version you are using. You need to look this up in your project

[kryptus36]

"name": "@nativescript-community/ui-lottie", "version": "4.3.0", "description": "NativeScript plugin to expose AirBnB Lottie library", "main": "lottie",

[farfromrefug]

@kryptus36 just released 4.3.1 which fixes urls like 1801-fireworks.json I didnt know about this syntax and it now works. About your latest issue it is a bit weird i cant reproduce it. Let me know how it goes with latest version

[kryptus36]

Seems to be working now. Much appreciated!
