[error] TypeError: Cannot read properties of undefined (reading 'document')

[amnweb]

There is output error on VScode start

[error] TypeError: Cannot read properties of undefined (reading 'document')

I have try to disable all extension only GistPad is enabled and error is still there.

• VS Code Version v1.81.1
• GistPad Version v0.4.1

i've noticed this a while ago, too. i disabled the extension because of it. 😞

recently, i wanted to use gistpad again, so i re-enabled the extension on the latest vscode:

the extension host log is filled with these messages; they are continuously logged, and can occur a few times each second. 😬

the messages appears to be logged when the window lacks an open document. 🤔 in other words, as soon as a document is opened, the logging stops. (FWIW, a diff view does not appear to count as a "document". only opening a real file on disk will stop the logging.)

the logging will restart at some point after closing the document. it's not totally clear what triggers it. 🤷
