Hi RLion,

The error says: or by rejecting a promise which was not handled with .catch().

You have to add:
.catch(error => console.error(error)
after the .then()

thus like:
restClient.newOrder({amount:10,price:100,side:“buy”,symbol:“btcusd”})
.then(response => console.log(response))
.catch(error => console.error(error));

Ivan tells this catch line later on…, but is needed!

I see that the quotes are different and changed to
restClient.newOrder({amount:10,price:100,side:“buy”,symbol:“btcusd”})
.then(response => console.log(response))
.catch(error => console.error(error));

now

A syntax error is a typo: somewhere a char is missing or has to be removed…
What is complete code?
javascript can be very strict… a comma missing or ; wrong…

key and secret are ok and not reversed?

see my post 4d ago:

I got “InvalidSignature” error message (due the added catch part, which must be available nowadays).
I saw : I exchanged the key and secret strings!
The key start with “account-”, one with “master-” does not work for me.

#157

maybe you know why the order cancels ??

return restClient.newOrder({ amount:1,
price:12000,
side:“buy”,
symbol:symbol,
options:[“immediate-or-cancel”]})

},

image

reason: ‘ExceedsPriceLimits’,

but 12000 is avobe current price so ???

#158

do not choose ‘too-high’… try somewhat lower

#160

Hello, I’m getting this message (below) when trying to install yarn on Mac terminal. I can’t imagine why this could be a permissions issue… any suggestions would be greatly appreciated.

Hi @ Ivan or anyone one else, I’m using a Macbook Pro. It seems there is a download version of Powershell for iOS, but I might also need something else to support it? Do you have any instructions geared twoard those of us with Macs? This is where I’m kind of stuck and it may take some time to figure it out. Any guidance is appreciated. Thanks!

#164

You can use terminal for macs. All instructions should be the same … I think.

Hi,
Can anybody help me with this issue?
I am at the stage of the Algo trading course where we need to install yarn to continue.

Everything went smoothly until this step.
Below is the command i entered into powershell and the error i recieved.
Any help much appreciated…

PS C:\Users\Andy\Desktop\Programming Course\Algo Course> yarn add gemini-api
yarn : File C:\Users\Andy\AppData\Roaming\npm\yarn.ps1 cannot be loaded because running scripts is disabled on this

I found the issue.
It seems that running scripts is disabled by default on windows.

@ivan
Maybe you could help with this issue, i cannot find the answer on Google

I am trying to create my first buy order after watching the lecture on “Gemini - Buy Order”.

I have the code written the same way you have it in the video but am getting this error from Powershell:

(node:4916) UnhandledPromiseRejectionWarning: #
(node:4916) 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(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 3)
(node:4916) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I see that someone else posted the same link that im posting but i have tried the solution to that issue and i get a different error where is does not recognize the .catch

I am very new to programming, sorry.
I have spent a good 2 hrs trying to solve this.

Many thanks
Andy
