Graphql makes error when returned list's length is 1

[seyoongit]

The code to reproduce this error looks like below:

schema.graphql

handler returns Integer Array which length is 1

I invoked graphql query in amplify-mock console http://10.220.190.149:20002/

It returns array of null which length is 5.

when value is 7, it will returns array of null which length is 7. when 123, Array of null which length is 123 on and on.

when returned array's length is equal or bigger than 2, it works well as expected

@seyoongit Thanks for cutting this issue, can you provide us more information? Are you using this directly with Amplify JavaScript, Amplify Console, etc. Also, can you provide your package.json along with your environment settings?

Please use the follow command:

npx envinfo --system --binaries --browsers --npmPackages --npmGlobalPackages

Thanks ahead of time!

sorry for late.

currently I'm using Amplify-Javascript (for web).

npx envinfo --system --binaries --browsers --npmPackages --npmGlobalPackages

Hi :wave: Sorry this was auto-closed by stale bot. We are working towards preventing this from happening in the future.

I noticed that in your schema you have lowercase [int] instead of capitalized [Int]. Did you correct this afterwards because that schema would not compile for mocking and would return this error.

Failed to start API Mock endpoint Error: Unknown type "int". Did you mean "Int" or "BigInt"?

[chrisbonifacio]

Closing this as stale as we don't have enough information to consistently reproduce. If you are still experiencing this issue in the latest version of the Amplify CLI, aws-amplify js library, and a graphql transformer v2 schema please open a new issue with steps to reproduce.
