I'm trying to call an API and once I have the response I want to target the image_url property but I'm getting this error Error in render: "TypeError: Cannot read property 'image_url' of undefined" and Cannot read property 'image_url' of undefined at VueComponent.getImages1 (Info.vue?42ed:39)

I've tested my code in another Javascript file and over there it works but for some reason not here. I've also checked for if the parent state is sending data correctly to child state through Vue console and it has worked.

I'm writing a simple memory game where the objective is to click on images.

Once one is clicked, the images will be displayed in a new order on the page. If you click on an image that you've already clicked on, you will lose and the game resets.

The problem I'm encountering is that upon rotating and displaying in a new order, the event listeners seem to have been wiped off of the images. No console logs show up after the new order is display, which should be happening.

The images are dynamically loaded from an array of images: None are static on the HTML page. Said images are appended to a Bootstrap-4 row.

I have a button that resets the images and sorts them in a new order via a sortArray() function. Said function is called in the imgRandom() function. This function is called whenever a button with the id #resetGame is clicked. the goal is to also call imgRandom() whenever an image is clicked, as well.

I've tried using $(row).empty to remove the images, but when I started to think it was removing the eventListeners, I tried using $(row).detach(), to no avail.

I need to group by a subset of columns and count the number of distinct combinations of their values. However, there are other columns that may or may not have distinct values, and I want to somehow retain this information in my output. Here is an example:

I am working with a simulated bebop 2 ,these are the commands I am using to run the simulation.

I've been publishing messages to a simulated Bebop2 launching the node with this commandroslaunch bebop_driver bebop_node.launch ip:=10.202.0.1 . I am trying to write a python script in order to do the same using this rospy.init_node("bebop_driver" ) , but I cant find the way to specify the ip.

These are the commands I am using to run the simulation.

Similar to the work done in this post I am curious to know if it is possible to do something similar with composite data types.

Example of what I'm attempting but have never seen it work.

I am working with the bebop_driver package and running the bebop_driver_node.

The bebop_node.launch file is like this:

I am attempting to create a really simple procedure that creates an account or several accounts. In order to accomplish this I wanted the implementation of the Call that will be made to this Procedure to be as simple as possible. The Code behind the Procedure can be complex or simple but that's not entirely what I care about here as I'm approaching this first from the perspective of the User that will be making the Call to the create_account() Proc.

Simple Call to Create an Account - As you can see in the code I provided there are Zero Declarations... I'm not initializing anything when making the Call. This is important to maximize the level of simplicity regarding the usage of this Procedure.

I am trying to receive some video from a Parrot Bebop 2 drone. I am using this Bebop.sdp file, which is supplied by Parrot.

I have previously tried in Python which worked by setting an environment variable OPENCV_FFMPEG_CAPTURE_OPTIONS to protocol_whitelist;file,rtp,udp. This worked in Python. Since then we have ported that project mostly to C#. But when trying to connect to the stream, we get this error Protocol 'rtp' not on whitelist 'file,crypto'!. I have seen other examples where this -protocol_whitelist "file,rtp,udp" is passed through ffmpeg arguments, but in this case it does not seem as a solution, since i cannot pass it on.

Firstly i started with a simple test:
