Persistent DuplicatedOperationError issues

Getting a lot of this when I first fire up our app for the day:

"Connection failed: {"errors":[{"errorType":"DuplicatedOperationError","message":"Duplicated operation with id 0fcfe9d7-afd7-46c6-bd80-3c2831381d89"}]}"

"Connection failed: {"errors":[{"errorType":"DuplicatedOperationError","message":"Duplicated operation with id 0fcfe9d7-afd7-46c6-bd80-3c2831381d89"}]}"

After a couple of page reloads, it stops. Should I be doing anything differently here? using fetchConnectionCache: true and using the non-pooled connection, via Lambda

What's your Lambda function timeout? I found that the default 3 seconds might not be enough with some databases from a cold start

ambitious-aquaOP•2y ago

like, a few minutes I don't think the default timeout is 3 seconds. should be 30, off the top of my head whoa, you're right. 3 seconds??!! that's nuts it used to be 30, back in the day 😄 ok, in our case I've set our timeout to 30 for all GraphQL resolvers

Yeah, I was surprised by that recently too. Fingers crossed it does the trick

ambitious-aquaOP•2y ago

yeah, def not related to Lambda timeout @Mahmoud any ideas? any recommendations?

plain-purple•2y ago

My bad. Sorry for the misunderstanding!

ambitious-aquaOP•2y ago

no worries 🙂

I’m not familiar with Amplify ( seems to be what’s reporting the error based on googling), hopefully Mahmoud has an idea

still seeing this message, typically as the DB warms up

"Connection failed: {"errors":[{"errorType":"DuplicatedOperationError","message":"Duplicated operation with id 1ba4aaf0-b6c0-4168-b845-9aaf9a0ab889"}]}"

"Connection failed: {"errors":[{"errorType":"DuplicatedOperationError","message":"Duplicated operation with id 1ba4aaf0-b6c0-4168-b845-9aaf9a0ab889"}]}"

@Mahmoud has anything been changed/improved in recent iterations? should I still be using the non-pooled connection and be setting neonConfig.fetchConnectionCache = true?

Let me check with the team and get back to you

ambitious-aquaOP•2y ago

thank you, much appreciated!

@Sam Hulick btw are you using the latest version of the serverless driver?

ambitious-aquaOP•2y ago

@neondatabase/serverless 0.6.1

adverse-sapphire•2y ago

the latest version is 0.7.2. do you mind updating and letting me know if the issue persists?

ambitious-aquaOP•2y ago

ah! forgot to run --latest on the pnpm update. lemme do that issue is still happening

exotic-emerald•2y ago

Hey @Sam Hulick , I'd be happy to jump on a call and see what's going on just to get a better understanding if that works. Early next week if we can't get it sorted by then? 🙂
