I'm trying to send an envelope created from a template in my account. But, I'm always getting the response:

HTTP Unauthorized 401 {"errorCode":"PARTNER_AUTHENTICATION_FAILED","message":"The specified Integrator Key was not found or is disabled. An Integrator key was not specified."}

Here is my code:

I'm trying to create a remote signing envelope that contains a pre defined template and a pdf that i generate on the fly. for that I'm using 2 composite templates joined together as mentioned here. for some reason when trying to send the envelope i get an error from the api:

I created a field in ACF plugin. I added the code below to show the data as a custom tab but the tab is always visible even if the field is empty. What am I missing?

So i am trying to get all of the server members with certain role with the following code

I see this example to use brave browser on windows. Is it supposed to work on Catalina as well by just replacing driver_path and brave_path?

Also, Chromedriver is only for Chrome. How to determine which version of chromedriver should be used for brave browser?

I have a project. I want to use tkinter and selenium. I'm telling a button to enter "https://stackoverflow.com" When I click it it opens but tkinter freezes. How do I get around this?

I am trying to log every time a user has logged in or logged out in Django. I am using the default login and logout views by Django. How can I implement logging these easily without the need for a model to store them? Only using logging also if possible that I can edit these default views in my views.py this can be much easier

My views.py code:

I am writing a client-server solution. The goal is to connect to a camera remotely and receive its camera feed in the client. I am using TCP protocol for this. Yes, this is the first time I'm doing this.

The client is written in Java. This means it uses BufferedReader.readLine(). Yes, the problem is that it results in null and I am aware that this means that the server shuts down the connection. I have also had this confirmed by a senior coder.

The server is written in C. My problem is that I cannot find an obvious reason to why its code results in shutting down the connection seemingly immediately. I have found multiple code-examples that supports the method I'm already using.

I wonder:

1. Could BufferedReader resulting in null immediately indicate something else in this case?
2. What have I missed in my server-code, why does it shut down the connection?

Here is my original server code (see update below it):
