What are technical and license Prerequisites to get started with AL programming

(0) ShareShare

Posted on by 58

Hi 

We have just set up a new Business Central system with Business Central Essentials license.

Then I have tried to follow this AL learning path Get started with development in Microsoft Dynamics 365 Business Central - Learn | Microsoft Docs

But I fail to succeed - I never get to the stage where the Hello World app is running - and if I can't even get the Hello World then this is going to be a tough and steep learning curve.

In stead i get an error message 

"The package cache c:\\myfolder\\AL\\ALProject1\\./.alpackages could not be found."

The folder where i placed my first project is c:\myfolder\AL\ALProject1 but the error message contains a lot of double backslash - c:\\myfolder\\AL\\ALProject1 - This looks strange, but I don't know if this means anything.

In the Output tab I also see some error messages:

[2022-01-05 09:43:46.23] Targeting Dynamics 365 Business Central.
[2022-01-05 09:43:46.24] Sending request to api.businesscentral.dynamics.com/.../metadata
[2022-01-05 09:43:46.60] The request for path /v2.0/sandbox/dev/metadata failed with code NotFound. Reason: Not Found
Am I missing some prerequisites or what is wrong.

    I should add that we run Business Central cloud version and that I have successfully created a sandbox.

    I think the issue is in your launch json file where you have not addressed your sandbox in the correct way.

    Make sure you have theese two properties are defined correct.

    "environmentType": "Sandbox",

     "environmentName": "YourSandboxName"

    Thanks Inge, I now got one step ahead.

    I was actually wondering how the program would know which sandbox to use, but as I have only one, I thought it might work.

    It is very frustrating that the tutorial does not mention this step, but thanks to you I can finally get started learning AL.
