JSON error when using express/node/react - node.js

Anyone know this error? https://imgur.com/a/8FhjxU1
"Unhandled Rejection (SyntaxError): Unexpected token P in JSON at position 0...
I don't know how an error message can get any more vague. I also followed a guide which apparently has worked for many people but for whatever reason I run into this error...
This is the guide I followed verbatim. https://youtu.be/8bNlffXEcC0
And I also followed other guides that are the same thing
But I keep running into this weird error message when it's time to display.
I'm guessing I have a weird version of node or something?

Issue with viewing data transformation with PyTorch

I am currently trying to process data for a simple network. This is the code I entered:
Screenshot here
I keep getting this error message but can't find any syntax problems or anyone else with this issue, I'm guessing it's something to do with my vienv because I've seen tutorials of people with no issues and that exact code. It's possible I haven't imported a package into my IDE and I am using anaconda and PyCharm if that helps.
Anyway, this is the error message I keep getting.

You need to use transforms.ToTensor() instead of transforms.ToTensor when passing to transforms.Compose.

backend.set_image_data_format('th') returning unexpected errors

I am trying to implement some code, and when I run my notebook, I have returned the following errors:
I am not too sure what I am doing wrong and why I am receiving this error. I have also tried to use set_image_dim_ordering but not luck.

i keep getting the error "cannot read property 'get' of undefined

Here's the link to the code on my 'Github' Please help me take a look
I kept getting this error being thrown back at me and I don't know why I've looked through the code multiple times but cant find anything.
So you are obviously getting the error thrown inside this switch there, between the lines 30 and 36, as you try to use bot.command instead of bot.commands ! bot.command is not set anywhere.

How to read node errors from the console?

I have this error in the console, below which gives the number 8301. What does this number mean and how can I use it to troubleshoot the error?
(node:8301) DeprecationWarning: current URL string parser is
deprecated, and will be removed in a future version. To use the new
parser, pass option { useNewUrlParser: true } to MongoClient.connect.
Pleas note, I am using this as an example error to try and understand the printed number (node:8301). I don't need help with the error itself.
Please help me to understand node errors.
The number portion of (node:8301) is the node process's process id (pid). This is attached to all warnings that Node.js itself emits, or that are emitted via its process.emitWarning() utility.
(In the particular example in the question, the warning is from a user module using process.emitWarning().)
For what it's worth, NODE_DEBUG also logs pids in the logged information, although strangely not in that format.
I'm not sure if there is actually official documentation on this. There is presently a discussion to add a "Warnings" section to the official documentation: https://github.com/nodejs/node/issues/24987
This question was also asked to https://github.com/nodejs/node/issues/25120, where I discovered and originally answered it.
try this:
MongoClient.connect("mongodb://localhost:27017/YourDB", { useNewUrlParser: true })

Honestly, I’ve been working in node since 2009, and I’ve never bothered to look into the error codes unless I need my software to handle the error. Mostly, I just read the error text.
In the case of your example, the error text clearly tells me what the problem is.
I’ve found generally that the quality of error messages and codes alike varies greatly on the library you’re using.

WinRT - Windows Store - WinRT Originate Error - How do decipher such an error?

I'm working on a Windows Store app and I'm getting a WinRT error that doesn't really give me any information so I would like to know how to understand these sorts of errors.
Basically I get the error on the following line which is called inside OnPointerPressed:
m_gestureRecognizer->ProcessDownEvent(args->GetCurrentPoint(nullptr));
The error is:
First-chance exception at 0x76F54B32 (KernelBase.dll) in DXAML2.exe: 0x40080201: WinRT originate error (parameters: 0x80070057, 0x00000044, 0x03CEE72C).
This error didn't used to appear, the only thing I've changed is that this line is now wrapped in an if clause which tests if the current pointer's PointerId is the same as one I've stored just using == such as:
if(args->GetCurrentPoint(nullptr)->PointerId == m_UIPointerID)
I have no idea why this has started happening.
So my question is in two parts:
More generally, how do I understand what an error such as the above means?
And does anyone know this error has suddenly started happening now that I check the pointerId?
Thanks for your time.
P.S. I guess another thing that has changed is that there will already be 2 pointers on the screen (the one that gets pushed into this GestureRecognizer) as well as another one, hence the PointerId check.
"How to Decipher such an error"...
For any WinRT originate error, you can take the third address in the parameters list (in your example, 0x03CEE72C), and find a description of your error in the memory window.
While debugging, break when your error is thrown and open the memory window via Debug -> Windows -> Memory -> Memory 1
Copy and paste the address to get your "easy-to-find" error message.
As Raman said - it's good to look up the hex values shown. The first one is the memory location which won't tell you much without the symbols/source, which in this case is reported directly by Windows. Perhaps the public symbols can shed some more light on where the error came from, but the error code lookups are more helpful.
If you Bing for 0x80070057 you will find an MSDN article on Common HRESULT Values which lists
E_INVALIDARG : One or more arguments are not valid : 0x80070057
It doesn't give you all the details of course, so you're off to theorize. Perhaps you can only call args->GetCurrentPoint(nullptr) once and you should store/reuse the value? Maybe gesture recognizer is not configured correctly? Maybe the app window is not visible at the time the exception is thrown or the thread is wrong. Maybe some expected calls to gesture recognizer were missed due to filtering those out with these "if" statements.
