Hi, I'm trying to run the codebase, I have Node 22, I ran

npm ci

with no errors, but when I try to run

npm run dev

in the server folder I got the next error:

npm run dev
@medplum/server@3.2.27 dev
ts-node-dev --poll --respawn --transpile-only --require ./src/otel/instrumentation.ts src/index.ts
[INFO] 20:26:46 ts-node-dev ver. 2.0.0 (using ts-node ver. 10.9.2, typescript ver. 5.7.2)

    at Module._compile (node:internal/modules/cjs/loader:1364:14)

I deleted the node_modules folder and tried again, but it didn't work, I also ran

npm update

but got the same result

Also a medplum user- Have you run [npm run build:fast](https://www.medplum.com/docs/contributing/run-the-stack#build)?

Thank you so much @nathan-watkins-unityai ! yes that would be my suggestion as well

I was facing this issue, until I realised I was running on node 20, I upgrade it to the latest, cleared node_modules and started again and it looks like is gone

Do you happen to know which version of node 20? I believe 20.10 is the actual minimum necessary as that's when node changed from

import assertions

to [import attributes](https://nodejs.org/api/esm.html#import-attributes), which [medplum uses](https://github.com/medplum/medplum/blob/b1ef1664e50e431e8fcd544ad565b6af93beef4d/packages/core/esbuild.mjs#L8) in several places
