Hi @88489754! I'm Dosu and I’m helping the dify team.

This is a known bug in Dify v1.9.2 (self-hosted, Docker) where paste (Ctrl+V) and other keyboard shortcuts are unreliable or non-functional in the code execution node. The issue is caused by a problem with the Monaco Editor integration and has been fixed in pull request #27282 by downgrading the @monaco-editor/loader package to version 1.5.0. To resolve this, update to a version of Dify that includes this fix, or apply the changes from the pull request if you are running a self-hosted instance. This should restore reliable paste and keyboard input functionality in the code execution node. You can find more details and confirmation from other users in issue #27293 and issue #27344.

To reply, just mention @dosu.
