Thank you for providing the instructions to replicate your changes. I found that the pims frontend hot reloads, but I wasn't able to get the pims backend to hot reload.
These are the steps I took where I made these observations.

Setup

1. Remove all containers manually through Docker Desktop
2. Remove all images manually through Docker Desktop
3. Remove all volumes manually through Docker Desktop
4. git checkout pims-hot-reload in the rems-setup repo
5. git checkout fix-hot-reload in the pims repo
6. Do git submodule update on rems-smart-on-fhir and rems-setup
7. Do git checkout dev on all other repos (not pims and rems-setup)
8. docker-sync-stack start in rems-setup
9. Go to http://localhost:5050/DoctorOrders
10. Click the Verified Orders tab
11. Observe the standard output rems_dev_pims container

Steps I took to observe the pims backend (hot reloading doesn't work)

12. Add a console.log("foo bar baz"); in the /api/getRx endpoint in pims/backend/src/routes/doctorOrders.js. I see this output in my local Terminal where I ran docker-sync-stack start in rems-setup:

13. Observe the standard output in the rems_dev_pims container. I noticed the console.log from step 12 didn't show up.
14. Repeat step 12 but with console.log('hello world');. I saw the same output:

Steps I took to observe the pims frontend (hot reloading works)

15. Click on the "Picked Up Orders" tab on http://localhost:5050/DoctorOrders
16. Replace <h1>PickedUpOrders</h1> in pims/frontend/src/views/DoctorOrders/PickedUpOrders/PickedUpOrders.tsx with <h1>hello world</h1>
17. Observe that the header text successfully changed to "hello world".
18. Observe the output in the Terminal where docker-sync-stack start was issued in the rems-setup directory.
