10/27/2021, 9:26 PMBefore I dig too much into this, thought I’d post here. I’m getting a syntax error when deployed, but not when debugging. (There are no ‘?’ in my function) so I’m thinking it’s a transpile issue with some package, but not sure. Wondering if anyone has seen this before I go digging:

10/27/2021, 9:28 PM@thdxr for what it’s worth, the problem function is basically a stripped down version of kysely + your dialect - wondering if there’s something in there that esbuild isn’t happy with?
Patrick Gold
10/27/2021, 9:28 PMOr rather, lambda isn’t happy with esbuild’s output

@Patrick Gold If you go into ur Lambda console, look up the function, and view it’s source code. What do u see on line 98?
Frank
10/27/2021, 9:34 PM
You can also see the transpiled code in ur
.buildp
Patrick Gold
10/27/2021, 9:34 PMThe source in lambda console is all on a single line
Patrick Gold
10/27/2021, 9:35 PMGood idea. let me check the .build folder!
Patrick Gold
10/27/2021, 9:35 PMHah - alas this was built by pipeline lol

Frank
10/27/2021, 9:35 PM
hmm… what u see in the .build folder should be the same as that uploaded to Lambda

Patrick Gold
10/27/2021, 9:36 PMI’m not that familiar with Lambda internals, but is /var/runtime/UserFunction a copy of the handler?
Patrick Gold
10/27/2021, 9:36 PMBecause that doesn’t appear to be from my file if not

Frank
10/27/2021, 9:37 PM
Oh sorry.. misread it… ur handler should be in /var/task
p
Patrick Gold
10/27/2021, 9:38 PMIt seems like this is lambda’s internal loader which does a syntax check beforehand

Frank
10/27/2021, 9:38 PM
u r right

Patrick Gold
10/27/2021, 9:38 PMit would be nice if it told me where the syntax error was 😄
Patrick Gold
10/27/2021, 9:50 PMpulling the source down, I don’t see any obvious syntax issues, though it is fairly obfuscated. Could it be a runtime mismatch?
Patrick Gold
10/27/2021, 9:52 PMYep, I think that’s it. Lambda is using Node 12 and locally I’m on 14
Patrick Gold
10/27/2021, 10:17 PMConfirmed. Issue caused by mismatched node runtime. Perhaps an enhancement to SST could be comparing local node runtime with deployed and showing a warning?
