NAV 2018 CU9 error in app.jason file

Hi Everyone,

I have tried to create a extension in AL code and when I was trying to publish it was asking to download the symbols but I was unable to download the symbols. So I have gone through with the app.jason file and found that below value

"platform": “12.0.0.0”,
"application": “12.0.0.0”,

Once I change the value from 12 → 10 I was able to download the symbols.
So I would like to know that is it a bug or do I need to change something in my setting while installation of VS code. Any help / suggestion .

"platform": “10.0.0.0”,
"application": “10.0.0.0”,

Neither 12.0.0.0 nor 10.0.0.0 is correct. You need to specify the same version as your installed NAV version. Version 10 is NAV 2017 and version 11 is NAV 2018.

Whereas if you download the Business Central dev. previews, then the current version is 12.0.0.0. When the next release is released then we have to use 13.0.0.0.

Meaning you should change it to 11.0.0.0 to make it download the correct symbols.

Thank you Erik for your descriptive ans.
