I’m sure this is a VSCode issue but I’m having issues debugging async functions when running from

sst start

. If the lambda is synchronous then it works great, but with some async functions (not all) the breakpoints bounce around when I click them. I know this means there’s an issue with the source maps but I’m a bit stuck. FWIW I am using the

launch.json

as recommended in the docs, and my

tsconfig.json

has (among a bunch of other things):

"target": "ES2018",
"inlineSourceMap": true,
"inlineSources": true,

Any tips would be greatly appreciated! The SO posts on this topic haven’t been useful so far.

Hey @Matt Rozema, is it always the same functions that have this issue? Or does the issue pop up randomly?

@Frank - when it happens in a specific function, the issue is always there. I had one specific async function where it was having that issue, but then I made the function synchronous and the issue went away. I think it's pretty clearly a problem with source maps but I feel like this shouldn't be a problem with the maturity of the tools. I feel like I'm doing something wrong but I don't know what it could be!

hmm.. let me loop in @thdxr. He’s more familiar with typescript and source maps.

Hm I don't think I've had to do anything with tsconfig to get breakpoints to work

I’m not certain - just speculating.

@Matt Rozema would it be possible to create a sample repo with this so we can try and reproduce it?

I can try! I'd have to detangle a few things first, which would probably be a good exercise anyway!

Thank you!
