Exceptions at startup of Coffee-Editor

[Truezer]

I'm testing Coffee-Editor and I wanted to know if the exceptions that appear are normal. Apart from these exceptions, it works with apparent normality

At startup I always get the following exception:

ERROR Could not initialize contribution TypeError: Cannot read properties of undefined (reading '_events')
    at _addListener (node:events:548:19)
    at addListener (node:events:605:10)

    at processTicksAndRejections (node:internal/process/task_queues:96:5)

When I access the url “http://localhost:3000”, I see the following exceptions (the order is not always the same):

2023-09-12T10:36:55.176Z root INFO [156dcb41-3a0f-42b6-a923-2898d9325309] Start of 9 plugins: 1662.0 ms [Finished 11.842 s after frontend start]

The following exception (as the stack is very long, I leave you only the root cause, does not always happen):

Caused by: java.lang.NumberFormatException: For input string: "home"
	at java.lang.NumberFormatException.forInputString(NumberFormatException.java:67) ~[?:?]

The last of the exceptions is the following:

Apart from exceptions, a warning appears multiple times:

root WARN Failed to register a menu item for plugin ms-vscode.cmake-tools contributed to touchBar {
  command: 'cmake.debugTarget',
  submenu: undefined,
  alt: 'cmake.selectLaunchTarget',
  group: 'CMake:run',
  when: 'cmake:enableTouchBar.debug && cmake:enableFullFeatureSet && !cmake:hideDebugCommand'
} getMenuNode@http://localhost:3000/bundle.js:60736:23

Thank you

HI @Truezer ,

sorry for the late reply. Are you running the docker image?
If you are not using the docker image, on which OS are you?
