JSON Parse error: Unexpected EOF when executing from console
Hi, I'm trying to test a piece of code and I can't figure out what I'm doing wrong. I've reduced the deployed main to just this
TypeScript
export default async ({ req, res, log, error }: any) => {
log(Date.now())
log(JSON.stringify(req, null, 2))
}
to debug. I'm trying to run an execution from the web console. Ive tried:
- setting/unsetting the
content-type: application/jsonheader - body: {}, "{}", {"actual": "json"}, '{"actual": "json"}', some text, "some text"
But no matter what, I get this in the error console
TypeScript

I'm using Bun1.1 as the runtime.
TL;DR
Developers are experiencing a JSON Parse error with the Bun1.1 runtime when executing from the console. The issue might be alternative runtime support. Solutions include porting to Node or ensuring a proper response is being returned at the end of the function. Finally, despite various test methods, the error persists, so further debugging is necessary.
you need to return a response
Same thing
TypeScript
export default async ({ req, res, log, error }: any) => {
log(Date.now())
log(JSON.stringify(req, null, 2))
return res.empty()
}
If i just log(req) then I get

Okay some more info: Deploying the same code with node22 works as expected. Trying to then switch this over to Bun gives me an error that npm is not installed
Sounds like the issue is with the Bun1.1 runtime, I'll try porting to node later to see if that fixes things, but the support for Bun is one of the main reasons I switched from supabase
