Because Iām new to this ā¦ Iām not sure how much information I should share. Iām happy to share a lot more with you over email. pjonson2@gmail.com.
So from the looks of it https://ly55wbovq4.execute-api.us-east-1.amazonaws.com/prod is not accessible. Either there is a typo there or it has not been deployed. Can you double check how you got that URL?
I pulled the URL from the following tutorial ā¦ Should it be something different?
I resolved the issue the URL was the wrong URL. I found the correct URL through searching on the AWS console for API Gateway. In the API Gateway if you go to stages on the left hand side and click on it the URL will be at the top. Also, I SPENT FOREVER WONDERING WHY THE COMMAND WAS WRONG!!! If you are a mac user ad you are getting the following error when you copy the command over
Missing required arguments: password, user-pool-id, app-client-id, identity-pool-id, invoke-url, path-template
it is because the terminal text has a different ASCII representation for the - character than what is represented in the latest version of chrome (Sep. 2018). You just have to type the entire command yourself.
Alright. I looked around my logs a bit more and saw something that might be helpful. Thanks so much for your help!

@jayair
I got it to work.
I think the error happened when I refactored my code for the create.js file.
I had left this part in my create.js file
AWS.config.update({ region: "us-east-1" });
const dynamoDb = new AWS.DynamoDB.DocumentClient();
while taking out the call to import AWS
import AWS from "aws-sdk";
Thatās why Cloudwatch gave the reference error.
I went camping for 3 weeks otherwise I wouldāve probably found it sooner.
Or maybe I found out the bug so easily because I left the tut for three weeksā¦
Either way
Thanks so much for your help!
OH yeah the URL is what we have in the tutorial. You need to replace it with yours.
Was the copy and Paste issue just on Chrome? Thatās really strange.
Glad you figured it out! Thanks for reporting back.
NOTE, no question:
Hey Guys,
i was trying to use the apig-test command on Windows with the command for windows specified in the chapter.
the were errors coming up.
`Path must be a string. Received undefined`
and
`SyntaxError: Unexpected token \ in JSON at position 1.`
The execution failed in the end and the API was not called.
Beware that this error occured with the Power Shell Terminal Application.
By running the code in the standard Command Prompt (cmd), the command worked perfectly fine (although the Path must be a string. Received undefined error still showed up) , the API request worked and a dynamoDB entry (according to the POST-function) was created.
Hope this helps someone
Have a great day
Florian

Thanks for posting about the issue. We havenāt offered a lot of support for Windows, so this should help.
When I hit this code below,
npx aws-api-gateway-cli-test \
I got only got this.
Authenticating with User Pool
Only custom auth (lambda driven) is enabled for this client.
Could you guys have any ideas to solve it???
This worked for me. Thanks.
I still dont know why because it worked once, then stopped.
Steps:
- Go to Aws IAM console.
- Search roles for
lambdaRoleand click to open role. - Click attach policies button and search for AdministratorAccess and attach it.
- Run same command that failed and it works. Didnt redeploy.
@jayair - Thanks for this wonderful tutorial, kudos!
I am getting the same cryptic 403 message that so many here have got. I went through the comments but wasnāt able to comprehend whatās going wrong.
Here is the request that I am making -
npx aws-api-gateway-cli-test --username admin@example.com --password Passw0rd! --user-pool-id us-west-2_kXXXeqxG --app-client-id QWmXXXv9m5p0u2ca0 --cognito-region us-west-2 --identity-pool-id us-west-2:1608cXXX420-9018-387bf6cb47c6 --invoke-url https://6rXXX2j2YY4.execute-api.us-west-2.amazonaws.com/prod --api-gateway-region us-west-2 --path-template /notes --method POST --body "{\"content\":\"hello world\",\"attachment\":\"hello.jpg\"}"
Response -
npx: installed 1 in 3.943s Path must be a string. Received undefined npx: installed 105 in 13.956s C:\Users\XXX\AppData\Roaming\npm-cache\_npx\19376\node_modules\aws-api-gateway-cli-test\index.js Authenticating with User Pool Getting temporary credentials Making API request { status: 403, statusText: 'Forbidden', data: { message: 'Forbidden' } }
I am using bash on Windows, but I tried the same in cmd and PowerShell as well. Also, I tried using .../prod/ as the invoke-url parameter, and notes as the path-template parameter, to which I get a 500 Internal Server Error.
Correspondingly, I realized that the formatting in the .yml file was incorrect, in that iamRoleStatements was indented similarly to provider. I corrected that but to no avail.
Here is what the CloudWatch log says -

Greatly appreciate the help 
@jayair - I feel stupid now. The same command worked in cmd for Windows, there was an issue with the terminal I was using.
Note: For Windows 10 users, prefer using the cmd prompt to execute these commands.

Glad you figured it out. Our Windows instructions arenāt great.
I canāt get past the āUser does not exist.ā message. No idea what Iām doing wrong or missing, but I recreated my identity pool, still says that I donāt have any users in it, but my cognito pool has the user in it created from the instructions. Not sure what Iām missing. Any ideas?
When are you seeing this error message?
Just when testing the API now that it exists in AWS now. Iām guessing I have something wrong with the user setup but I havenāt found where yet. I see this error from the cli after I call the test method that is supposed to create a record on the server.
