Posted on by Roberto Suarez Alemany

Hello,

My project is working fine, I can compile and run the package in my sandbox but when I try to use the feature F6 in order to run the Business Central in mode Designer I receive this error message.

What should I do to solve this problem?

Thanks in advance,

I have installed these extensions but still received the error message when I try to run the "Command Palette" -> " AL: Open in Visual Studio Code Designer".

Hi,

May be this help something

We no longer need to get the next AL Language extension version from preview containers, now they provide this directly through pre-release versions of the extension in VS Code

This indeed was a bug and is fixed in the current prerelease version of the AL Language extension: v12.0.800702.
