OpenCR | OpenCR | Robotics library

I am working through a short tutorial (see link below) to publish an image stream in ROS Raspberry Pi camera: https://www.theconstructsim.com/publish-image-stream-ros-kinetic-raspberry-pi/.

I have ignored the steps to install Ubuntu mate OS on the raspberry pi as I have already completed this when completing the Turtlebot3 tutorial from Robotis (see link below): https://emanual.robotis.com/docs/en/platform/turtlebot3/setup/#setup

I have completed the steps to "Get the LCD screen up and running" with no issues.

I was unsure if I should install the Full ROS Kinetic, as I completed this during the Turtlebot3 tutorials (link above). Am I incorrect in saying this? The Turtlebot tutorial set up both the Remote PC and the Turtlebot robot (including the raspberry pi and the OpenCR setup).

I am running into issues on the "Setting up raspberry pi camera" section.

This is the following code and error I am receiving;

I have a Web App that runs fine and creates a Google Doc. That app is installed in a button on a new Google Site. Sometimes, I need to create a new doc from the Site, but sometimes I need to create a new doc when I have a Google Spreadsheet open (which sheet contains data relating to the Site and that is embedded in the site).

I have a custom menu on that sheet that does a number of different things. I want to add an item to that menu that accesses the Web App described above and runs it.

First of all: Is this possible?

Second, I assume if it is possible, then somehow, I have to call the Web App script using its URL (as I do with the button it's attached to on my Google Site).

My Web App code is below:

The following code opens a spreadsheet. What is strange is the portion of the ss that is visible. The ss has around 430 lines (I say "around" as the script adds lines, so how many it has at any given time depends on how many tests I have done of the script and how many of those test lines I have deleted). But, no matter how many lines the ss has or what lines are visible before I run the script or where the cursor is on the ss before I run the script; when the script runs, when the ss first opens, the top portion of the ss is visible (pictured below) and then as the ss is still loading (working), the page redraws and line 396 (or 397, 398, etc., depending on how many tests I have run and/or deleted) is always the first visible line (also pictured).

There is an "onOpen" script that affects the ss (creates a menu), and in order to rule that out as a factor in your minds, it is also reprinted below.

So, what is controlling this redraw process and how do I get it to give me what I want which is to see the bottom of the page? I want this line to be visible as the next logical thing for the user to do after they have added a new song is to add the data for that song.

I am trying to open google sheets from a custom (bound) menu in another sheet. The scripts "run" but do not open the sheets I am trying to open (by "open, I mean, they are not visible in a new browser tab).
