Reproduction steps are missing, so start by reproducing the reported debugger:show flow after run:file and a gutter click on Atom 1.57.0 with ide-python 1.9.7. Read the stack locations in react-dom.production.min.js, ReactMountRootElement.js, pane-element.js, and DebuggerLayoutManager.js, especially the listed entry points. Done means the debugger view opens without the uncaught TypeError.
