FCC - Exercise Tracker cannot pass on test 7 and 8 please help

Tell us what’s happening:
When I ran the test, I cant pass on test 7 and test 8.

Test 7:
You can POST to /api/users/:_id/exercises with form data description , duration , and optionally date . If no date is supplied, the current date will be used.

Test 8:
The response returned from POST /api/users/:_id/exercises will be the user object with the exercise fields added.

the desired result is showing when I fill out the form manually but when I run the test, it always fails saying : TypeError: Cannot read property ‘username’ of null.

I am encountering this error when I run the test: (error attached).

throw er; // Unhandled ‘error’ event

The issue/error is specifically happening in the response.json object. I attached the screenshots of the server.js code.

Log your route inputs and the updatedRecord and you’ll see the problem:

app.post(apiUserExcercisePath, (request, response) => {
  console.log(`req.body: ${JSON.stringify(request.body)}`);
  console.log(`req.params: ${JSON.stringify(request.params)}`);
  console.log(`req.query: ${JSON.stringify(request.query)}`);

  let userId = request.body[':_id'],


req.body: {"description":"test","duration":"60","date":"1990-01-01"}
req.params: {"_id":"61bfd87a37f438010b39fd87"}
req.query: {}

and updatedRecord is


Look closely at how you define userId and where the _id is set. The find() that sets updatedRecord does not have the correct input.
