Model Editor in Infinite Loading State with no error message

Bắt đầu bằng cách tái hiện hai kịch bản với ứng dụng Java mẫu được liên kết, sau đó kiểm tra luồng Model Editor và các log của extension và CodeQL Query Server xung quanh ApplicationModeEndpoints.ql và FrameworkModeEndpoints.ql. Công việc được xem là hoàn tất khi cả hai trường hợp lỗi đều hiển thị một lỗi hữu ích thay vì để bảng điều khiển lập mô hình Java tải vô thời hạn.

Describe the bug
Under some specific circumstance(s) the model editor gets into an infinite loading state, with no error message about what has gone wrong.

Version
The CodeQL and VS Code version in which the bug occurs.

VSCode CodeQL Extension version - v1.13.1
CodeQL CLI versions tested with: 2.16.3, 2.17.1, 2.17.4, 2.17.5

To reproduce
There are 2 scenarios where I have observed this. In scenario 1 , I admit that I am aware of the fact that the database has a missing file, and then perhaps this behaviour makes sense? (though I still think it would be hard to debug without an error message). In scenario 2, I do not know what the underlying issue is.

Both scenarios use the sample Java app in this repo

Scenario 1)

1. perform:

javac SampleInner.java
codeql database create -l java databasenoinnerpresent --command='javac Sample.java'

successfully creates a database with no SampleInner.java file (probably this causes the silent error?)

2. load the database into the editor
3. open the model editor

end of CodeQL Query Server log shows:

CLI command succeeded.

Scenario 2)

1. perform:

javac SampleInner.java
codeql database create -l java databaseinnerpresent --command='javac -cp . Sample.java'

successfully creates a database with both, as expected, Sample.java and SampleInner.java file

2. load the database into the editor
3. open the model editor
4. select "Model as Dependency"

end of CodeQL Query Server log shows:

CodeQL Extension log tail:

CLI command succeeded.

both yield a infinite Modelling Java panel like:

Expected behavior
I expect a failure message to display so that the reasons for the hang can be fixed (ie if there is something wrong with a database then how would a user know that unless there is some error message). I am not currently sure why I cannot model the database in the example as a dependency...

Additional context
Add any other context about the problem here.
