Debugger crashes: Please improve exception handling and error messages

[DanielGoehler]

Please include the following with each issue:

1. Describe the bug When I try to open the global varibales in a debugging session for a cloud sandbox, the debugger crashes. Unfortunately, the only error message I get is "Error: Object reference not set to an instance of an object.". It would be nice if the AL Language Extension exception handling was better and there was a clear and unambiguous error message so that I can create an issue with more details, other than it crashed, other than the object reference was not set to an instance of an object.

2. To Reproduce Steps to reproduce the behavior:

1. Debug in a Cloud Sandbox
2. Run into an error
3. Expand the Global Variables

3. Expected behavior Debugger should not crash

4. Actual behavior Debugger crashes

5. Versions:

• AL Language: 10.2.719883
• Visual Studio Code: 1.73.1
• Business Central: DE Business Central 21.1 (Plattform 21.0.48357.50310 + Anwendung 21.1.48363.48789)
• List of Visual Studio Code extensions that you have installed:
  • AL Language

Final Checklist

Please remember to do the following:

• [x] Search the issue repository to ensure you are reporting a new issue

• [x] Reproduce the issue after disabling all extensions except the AL Language extension

• [x] Simplify your code around the issue to better isolate the problem

I get this one too, specifically, when I want to see global variables of a report.

[f0ffee]

Same here (same version of vsc and AL), opening both global and local variables in any kind of object, debugging an OnPrem Docker environment. Debugging has become overly annoying.

[christianbraeunlich]

Have you tried the fix mentioned in https://github.com/microsoft/AL/issues/7225?

[DanielGoehler]

@christianbraeunlich What do you mean exactly? The use of the Insider Preview AL Language Extension instead of the current stable version?

[nndobrev]

@DanielGoehler the fix @christianbraeunlich is suggesting is not a vsix fix, it is server fix and it can be found in either Insider builds or it will become available with 21.3. We will also take a look at this issue and if they are related.

[kalberes]

@DanielGoehler It would be nice if you could share a DebuggerServices.log (how see: #5882). Else an issue like this will be buried with a not repro. Also since you are using docker, do you have any relevant debugger info in your docker event viewer for teh running NST? I mean there must be something specific to your and @f0ffee else we would get a storm that people cannot debug. Isn ' it? Would be nice to find what is that. And then we will fix the issue.

[DanielGoehler]

@nndobrev Unfortunately, I don't know how to update a Cloud Sandbox to an Insider build.

[DanielGoehler]

@kalberes Attached is the DebuggerServices.log with cleaned up sensitive information. Unfortunately, I did not find any helpful information in it.

For me this is way too much work to create a Docker, connect them to Dynamics 365 Sales to get the event log. I'm not even sure if the cloud sandbox can be connected exactly like the integrated connection in the cloud.

But if you tell me how to get the cloud sandbox event log, I'll be happy to provide it.

@kalberes You can reproduce the problem if you set up the dataverse connection on your BC sandbox and run this report. The debugger stops at the error, when you open the globals, the debugger crashes with the error: Object reference not set to an instance of an object.

report 50000 Test
{
    UsageCategory = ReportsAndAnalysis;
    ApplicationArea = All;
    ProcessingOnly = true;

    dataset
    {
        dataitem("CRM Account"; "CRM Account")
        {
            trigger OnAfterGetRecord()
            begin
                Error('Random Error');
            end;
        }
    }

    trigger OnPreReport()
    begin
        Codeunit.Run(Codeunit::"CRM Integration Management");
    end;
}

@christianbraeunlich @nndobrev @kalberes Please keep in mind, the intention of this issue was not to solve this problem. My intention was to improve the general error situation of the AL Language Extension. I need a proper error message to make a good error report here.

I have a lot more crashes and unhandled exceptions that I want to report, but with error message like Object reference not set to an instance of an object where I literally don't know what exactly is causing the problem and I really can't narrow it down reasonably to report.

[kalberes]

Thanks, there is really nothing in the log file. I thought that you are using a docker based solution. We will probably accept is an issue and try to figure out why external tables are killing teh debug adapter. Apparently they do, so please triaging team this should be a high severity issue (S 1).

[nndobrev]

Hi @DanielGoehler, I think we actually fixed the issue, but can you please confirm that you don't see the issue if you are expanding the globals when within method scope of a Page object instead of Report?

[deadmouse]

I get this one too, specifically, when I want to see global variables of a report.

@nndobrev For me it keeps throwing error in a report when viewing global variables. Version: SAAS - ES Business Central 21.2 (Plataform 21.0.49939.51260 + Application 21.2.49946.49990)

[nndobrev]

Fixed from our side, since it is server fix expect it coming with 21.3 and also with the next week's insider builds. :)

[DanielGoehler]

@nndobrev Sure, I will test this once 20.3 is available for Cloud Sandbox.

Has the handling of exceptions and error messages also been improved, or has it only been solved around this particular example?
