ERR document already exists, ERR Unable to retrieve document from URI

[cjbd]

Hello, I'm not sure if this is openvscode-serve issue or upstream vscode issue, since version 1.78 or 1.77, I kept getting 2 error messages at the same time in browser console:

• 'ERR document ... already exists'
• 'ERR Unable to retrieve document from URI'

for the same file when I was editing it, and there're 2 editor tabs open at the same time for the same file

i never seen this using official vscode desktop version, my network is fine, my openvscode-server is served over https

also i have multiple instances of openvscode-server serving from same server but with different port, the other one seems to be fine...

the one with issue, i used it to develop vscode extension, so i have 2 windows (one spawned from F5 -> Launch Extension) open at the same time usually, does this matter?

anyone else came across this?

thank you!
