MIT App Inventor Help

The api is made with python and flask

5

Go on, what are its parameter requirements, are there any data submission examples?

6 
@app.route('/api/register', methods=['POST'])
def register_user():
    data = request.json
    email = data.get('email')
    password = data.get('password')
    username = data.get('username')
7 
Do It Result: "{"email":"test@gmail.com","password":"test password","username":"s4il"}"

Are you sure?
A screenshot would help to avoid misunderstandings...
I would remove that JsonObjectEncode block
Please show us a screenshot next time

Isn't that localhost?

Is your app talking to itself?

Maybe you need to specify content type in some headers?

I don't undestand what you mean by data submission examples

16

Maybe! How do you do that?

Ok, this looks better...
The difference was the double quotes at start and end

The companion says error 1110: the specified request headers are not valid: element 1 is not a list

That worked! The regster endpoint worked and created an account but for some reason it says eror 201, no idea what that is but this is what the logs say:

/var/task/google/cloud/firestore_v1/base_collection.py:303: UserWarning: Detected filter using positional arguments. Prefer using the 'filter' keyword argument instead. return query.where(field_path, op_string, value)
