Reproduction

try to parse incoming cookies (must be a Cookie header containing multiple values) with UseCookie in the lambda handler
It will find the first cookie and put the rest of the string as a value

Describe the bug

In the aws-lambda deployment setting in aws-lambda.mjs in the handler function, there is this line:

if ("cookies" in event && event.cookies) {
    event.headers.cookie = event.cookies.join(",");
  }

I guess you are trying to rebuild the Cookie header string content from the API Gateway incoming request headers.
However in the Cookie specification , each value is separated by a ";" and not a ",".

This behaviour causes the cookies to be wrongly parsed which can cause lots of problems to any apps

To fix the bug, I simply changed the snippet above to:

if ("cookies" in event && event.cookies) {
    event.headers.cookie = event.cookies.join(";"); // Notice the semicolon as a the join parameter
  }
