快速请求中止

Question

I am using Express.js to implement my backend. I often got the error. I don't know why.

I put the source code to AWS Elastic Beanstalk and set the ELB. If this error triggers more times, it will make all users cannot connect to the server. I always restart the Beanstalk instance to fix this problem. But I don't know when will trigger this error. So please help me to fix it.

Thanks a lot.

This error will occur when the request is aborted by the client before reading the body has finished. The status property is set to 400 and type property is set to 'request.aborted'. Please put the setup express code!
