I programmed some server command by my own. That server commands worked fine for a long time.
Suddonly I received
Studio Action "Attempted Edit" not supported on 127.0.0.1:57772[CTAE01]
by using one of my server commands.
There is an explanation:
Error running command vscode-objectscript.serverCommands.contextOther: Running the contributed command: 'vscode-objectscript.serverCommands.contextOther' failed.. This is likely caused by the extension that contributes vscode-objectscript.serverCommands.contextOther.
