Designer can't start

[matthias-planzer]

The Server gives the following Error when I try to start it with f6 (Starting it via "Forbidden Button" on the WebClient works.)

RootException: InvalidOperationException

Please include the following with each issue:

5. Versions:

• AL Language: 9.4
• Visual Studio Code: Newest (1.70)
• Business Central: CH Business Central 20.0 (Plattform 20.0.37114.38150 + Anwendung 20.0.37253.38230)
• List of Visual Studio Code extensions that you have installed:

Does this repro on a basic AL:GO project on the latest VSIX, or does it require a specific project setup?

[matthias-planzer]

Very likely not. This only happens in one project. It seems to be app related because this happens both on the CRONOS DB as well as the Customer DB. I was hoping the stack trace should be enough to fix this from Code Reviewing this, but unfortunately I don't think I can give you much more input here.

@thloke @matthias-planzer This looks to be a bug on the platform which appears to fail if there are more than two versions of the same application published for a given application. Unpublishing the one that isn't installed should be a workaround, until a fix is implemented, which should be to pick the one that's currently installed.

Hi, this issue is out of scope of for this repository. You should do one of the following:

• Open a support request to CSS through the PartnerSource portal
• Open a bug in Collaborate
• Contact your Service Account Manager (SAM) in your local subsidiary to understand what is included in your contract as of support incident and PAH (Partner Advisory Hours). Your SAM might also direct you "step by step" how to open a support request or how to get credentials, if this is the first time for you or your company

As a reminder, this repository only handles issues to do with the compiler or VSCode development experience for AL.

Just an additional note on why this is out of scope: this is an error in the server itself, so it needs to be looked at by the team that handles the server runtime - which is not part of the scope of this github repo.
