vscode-esp-idf-extension: [Bug Report]: QEMU Doesn't Launch: "Cannot read property 'fsPath' of undefined" (VSC-853)

Describe the bug The QEMU feature does not launch.

I click the [ESP-IDF QEMU] link on the activity bar. It creates merged_qemu.bin, and then prompts me to select Start QEMU. Immediately a status box appears “Cannot read property ‘fsPath’ of undefined”.

To Reproduce I am following the QEMU steps here: https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/QEMU.md

I created the Hello World example using the ESP-IDF: Show Examples Projects in VSCode v1.65 on Windows 11. The I opened the container using VSCode’s dev container support. It opens and builds the container.

(Side note: The first thing that VSCode complains about the “ESP-IDF” configuration in c_cpp_properties.json has a bad “compilerPath” because it is still referencing the windows path. I can fix this manually but it would be nice if this was taken care of automatically somehow. Obviously if I go back to developing without the container in Windows the path is again invalid.)

When I run “Build your project” it fails because I had already built the project in windows. So I remove the windows built ‘build’ folder. It then builds successfully.

I then click the [ESP-IDF QEMU] link on the activity bar. It creates merged_qemu.bin, and then prompts me to select Start QEMU. Immediately a status box appears “Cannot read property ‘fsPath’ of undefined”.

I have figured out how to manually get QEMU running and launch a gdb session through VS Code so I know all the tools and files are there correctly.

Expected behavior QEMU would launch, something like: qemu-system-xtensa -nographic -gdb tcp:3333 -S -machine esp32 -drive file=build/merged_qemu.bin,if=mtd,format=raw

gdb build/merged_qemu.elf would also run with the following start up commands:

target remote localhost:3333
monitor system_reset
tb app_main
c
