I may have found a little buggy issue with sst and Python lambdas: • I have a Lambda, called

KAR_ROT_complete_performance.py

, which puts a

PerformanceCompleted

event on my event bus. Works great, works great, returns a result with

"FailedEntryCount": 0

- all good. • Then, I have a Lambda, called

KAR_HST_add_performance.py

, that consumes said event and places it in a performance history dynamodb table. • If I do a

npx sst deploy --stage test

and then POST to the API to complete a performance, everything works great. No errors in the CloudWatch logs, and I can see my performance in the performance table. So, it works end-to-end with a

deploy

. • If I do a

npx sst start --stage test

, my

KAR_ROT_complete_performance.py

still works well, but my

KAR_HST_add_performance.py

throws the following exception in the terminal:

2d5b30dd-1daa-4bb4-af6b-da4ea4e975cf REQUEST test-karaoke-performance-his-historylogger7C190503-GGOSGWNuWwtH [src/services/performance-history/KAR_HST_add_performance.handler] invoked
SyntaxError: Unexpected token n in JSON at position 0
    at JSON.parse (<anonymous>)
    at createStrictSyntaxError (/home/lukewyman/Documents/code/karaoke-backend-sst/node_modules/body-parser/lib/types/json.js:158:10)

• I've also simplified the subscribed lambda so that I'm not trying to do anything at all with the event:

def handler(event, context):
    print('Inside the add performance handler!')

and I still get the exception shown above, while also printing

Inside the add performance handler!

to to the terminal. So, somehow, the subscribed lambda is falling apart with Live Lambda, but working as expected when deployed.

Hey @Luke Wyman, hmm… are

PerformanceCompleted

and

AddPerformance

in the same stack?

PerformanceCompleted

doesn't really exist outside of being the

detailType

string in my event bus rule in my

EventBusStack

. Over in the

RotationsStack

where the performance is actually marked complete, It's an environment variable for the Lambda that will

put_events

, and over in

PerformanceHistoryStack

, I've passed in the event rule so that the

AddPerformance

can be subscribed to it.

sorry i meant

KAR_ROT_complete_performance.py

and

KAR_HST_add_performance.py

, are they in the same stack or separate stacks?

KAR_ROT_complete_performance.py

is in the

RotationsStack

while

KAR_HST_add_performance.py

is in the

PerformanceHistoryStack

. The

EventBusStack

is shared between the two as needed to make the pub/sub for the custom event bus happen.

I see. Let me try to reproduce this.
