Hello everyone,

I am new to BC development, I am trying to connect BC sandbox environment hosted in the cloud to Visual studio code, but when I try to download the symbols I receive the following errors

[2021-09-17 11:52:56.12] The request for path /v1.0/sandbox/dev/packages?publisher=Microsoft&appName=System Application&versionText=18.0.0.0 failed with code NotFound. Reason: Not Found

Could not download reference symbols. Please ensure that:
1. The correct server name and instance are specified in the launch.json file.
2. The correct application version is specified in the app.json file.

bellow are my app.json and launch.json config

app.json

{

  "runtime": "2.0",
  "idRange": {

    "to": 60005
  }  
}

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Microsoft cloud sandbox",
            "type": "al",
            "request": "launch",
            "startupObjectId": 22,
            "breakOnError": true,
            "breakOnRecordWrite": false,
            "server": "https://businesscentral.dynamics.com/",
            "tenant": "**My tennant ID**"
            
           

        }
    ]
}

This are the details of the sandbox environment

and this are dependencies which I targeted in the app.json

I have tried to use the sandbox name property in the launch.json but this did not work, and it produced the same error message. Also for some reason which is not clear to me, when I add the property VS code shows the property is not allowed

In order to download the symbols I have also tried to clear my credential cache but this did not help

I have the same question (0)

Please remove dependencies in app.json

just application and platform properties are enough.

Hi!

Remove "server" from launch.json and add

"environmentType": "Sandbox",

"environmentName": "Your sandbox name"

Default sandbox name is "Sandbox" also

The tenant ID is shown in the Help and Support page in your Business Central. Make sure you have

"tenant": "<id_from_BC>" in your launch.json

Hello Neil, the tenant id is already in the launch.json, if you are looking at the screenshot is not visible because it's actually behind the intellisense error message text.

Hello everyone,

Thanks for all the answer, definitely helped stare me in the right direction. At the end I found a solution, basically it was a combination of things. Just writing my solution here in case someone runs into my same issue.

- Make sure your VSCode version is updated, if you don't see new updates download the latest version of vscode and re-install it.

I think that I was receiving intelissense warnings because although I had installed the AL Extension in VsCode, I assume that the extension version which was installed was not the latest, because my VsCode was not the latest. I realized that because although no new update will show (every time that I tried to update via Help -> Check for update), when going to the Help -> About I will see that my version number was not the same version number documented on Visual Studio Code Update Page and also I could see an i32 bellow the OS info which looked suspicious

- as Andrey Baludin mentioned, make sure you have environmentType": "Sandbox" and "environmentName": "Your sandbox name" are set correctly.

these should match the environment information's you can find in your BC admin portal, for the environment you want to target.

- Make sure that the user you are using to authenticate/set up the connection between VsCode and BC Sanbox, has the D365 EXTENSION MANAGEMENT and D365 Read permissions
