I am trying to access the variable set in one task from another task in JavaScript.

In the first task I am setting the variable as following:

var connection = tl.getInput("connection", true);
if(connection !== undefined) {
   var auth = tl.getEndpointAuthorization(connection, false);
      
   let access_key_1 = auth.parameters["password"];
   let username = auth.parameters["username"]; 
      
   if(auth !== undefined) {
       
   console.log('##vso[task.setvariable variable=access_key_1;]', access_key_1);
}

In the second task i am trying to access the variable:

console.log(access_key_1);

But I am getting error:

ReferenceError: access_key_1 is not defined.
