Hey @VincentC, hope you are ok.
As @cryptoforyou has mention, your declaration if incorrect.
You have getALLSymbols() where it should be getAllSymbols.

Please can someone help me. I’m on lecture 14 of the bot programming section and everytime I enter node index.js it keeps showing me this warning:
(node:10140) UnhandledPromiseRejectionWarning: #
(Use node --trace-warnings ... to show where the warning was created)
(node:10140) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

If anyone can assist I would really appreciate it! Thanks

i keep getting this error code. what am I doing wrong?
Hi Vincent, I think I managed to solve it. I was incorrectly adding npm to wrong directory. Thanks for responding, I’ll definitely be in contact if I run into any other errors!

did you add it with yarn? make sure gemini api file is in your code folder. If not, then it may still need to be added.
great, so it is working now? Sorry i was late to your replies
Yes I installed yarn and gemini api file is in the folder, I followed exactly what Ivan did in the videos. I keep getting a ‘Unhandled Promise Rejection warning’.
@ivan. the “yarn add gemini-api” does not work as your video shows. I keep getting a security error. how do I move forward?

Hey @cryptatticus, @VincentC, hope you guys are great.
The issue you have is with powershell, try to run the same commands with CMD (windows console), you can try npm install gemini-api if you have npm installed, yarn is another package manager like npm, you can also install it with npm install yarn.
Then the problem that you mention @VincentC:
Means that one of your functions should be asynchronous function.
Please provide your code in the following way so i can be able to test it for you and check what errors did you have on it:

I think Binance does not have an exchange sandbox (which is the platform for fake money), so no environment like binance but with fake money 
. (thats why we pick gemini for the course, they do have a sandbox to play around).

You might have an issue with yarn installation on powershell, you can try run the yarn command in CMD (windows console) and check if it returns a different message.
But you do not need to use yarn add gemini-api to install it, when you run npm install gemini-api is the same command has the first one (yarn or npm are package managers).
So after you have installed gemini-api through npm, you should be able to invoke it on your code by:
const restClient = new GeminiAPI({ key, secret, sandbox: false });

Loving the course @ivan and @filip,
