[BUG] TypeError: Cannot read properties of undefined (reading 'editor')

[Cito]

Describe the bug

After starting Obsidian, the following error message appears in the developer console:

app.js:1 TypeError: Cannot read properties of undefined (reading 'editor')

To Reproduce

Steps to reproduce the behavior:

Just starting Obsidian is enough. The current page doesn't even need to include an outline.

Expected behavior

There should be no error messages in the console.

Screenshots

If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• OS: Windows 11
• Obsidian Version: 1.5.3
• Plugin Version: [e.g. 4.6.2]

Additional context

I would investigate and try to provide a PR, but currently I'm not sure whether this plugin is still maintained given that no updates have appeared since months though many bug reports have been accumulated.

Same issue here, upon launch of Obsidian app, causes delays with "launching..." screen while the following is displayed to console repeatedly. Have been running the plugin without issue for 1-2 years.

OS: MacOS
ObsidianVersion: 1.5.3
Plugin Version: 4.8.0

export function getEditorFromState(state: EditorState) {
  const markdownFileInfo = state.field(editorInfoField);

  try {
    if (!markdownFileInfo.editor) {
      return null;
    }

    return new MyEditor(markdownFileInfo.editor);
  } catch {
    return null;
  }
}

It probably doesn't fix the issue, but you can hide the message by wrapping the function with a try-catch block.

Same issue here, are there any news ? Thanks.

Describe the bug
Your plugin is giving me the "TypeError" in the console, clogging the console in the developer tools.

To Reproduce

Download Outliner
Open a note.
Check the developer tools (ctrl + shift + i)
See Console TypeError.
Expected behavior
A clear and concise description of what you expected to happen.

I expected it to work normally without it giving any errors.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

OS: Microsoft
Obsidian Version: v1.5.8
Plugin Version: v4.8.0
Additional context
None.

export function getEditorFromState(state: EditorState) {
  const markdownFileInfo = state.field(editorInfoField);

  try {
    if (!markdownFileInfo.editor) {
      return null;
    }

    return new MyEditor(markdownFileInfo.editor);
  } catch {
    return null;
  }
}

It probably doesn't fix the issue, but you can hide the message by wrapping the function with a try-catch block.

Where do you put that?

I just put it as javascript and it works:

function getEditorFromState(state) {
    const markdownFileInfo = state.field(obsidian.editorInfoField);

    try {
        if (!markdownFileInfo.editor) {
            return null;
        }

        return new MyEditor(markdownFileInfo.editor);
    } catch {
        return null;
    }
}

Out of sight, out of mind.
