AWS User Pool Pre token generation Lambda trigger create and delete fail

[wzhonggo]

Hi,

I'm attempting to update the runtime from nodejs20.x to nodejs24.x (as supported by #123), which required upgrading oss-serverless/serverless (osls) from version 3.52.0 to 3.61.0. However, after running "sls remove", I encountered the following error.

You need to manually delete the trigger in the AWS userpool console.
When using the sls deploy command, it will remain in the CREATE_IN_PROGRESS state.

serverless config

   preTokenGenerationTrigger:
     disableLogs: true
     handler: preTokenGenerationTrigger.main
     description: "Amazon Cognito invokes this trigger before token generation allowing you to customize identity token claims."
     events:
     - cognitoUserPool:
         pool:  ${file(../../../${self:custom.stage}.config.yml):COGNITO.userPoolName}
         trigger: PreTokenGeneration
         existing: true

Could someone please help investigate if this is a compatibility issue between the new nodejs24.x runtime support and Cognito custom resources in the latest osls version? Any guidance on how to resolve this deployment issue would be greatly appreciated.
