I believe i found the possible error in my code, I have "n-ethereum-ropsten" as the chainID and not n-ethereum-goerli,

let me change this, re-bootstrap my CDK and test

Also, the link with the api gateway (https://APIgatewayID.execute-api.us-east-1.amazonaws.com/prod/account) returns:
{"message":"Unauthorized"}

from simple-nft-marketplace.

It seems that you are not logged in. Did you create your account first? If so, did you login to the system? Also, you can confirm your account existence on Congito on AWS Management Console. Did you provide user pool id environment variables to the frontend? Please check the above. Thanks for trying!

from simple-nft-marketplace.

Yes, I can see my created account in AWS Congito, and all 4 environment variables:

cat <<EOF > .env.local
VUE_APP_AWS_REGION=<region>
VUE_APP_API_ENDPOINT=<api-endpoint>
VUE_APP_USER_POOL_ID=<user-pool>
VUE_APP_USER_POOL_WEB_CLIENT_ID=<web-client>
EOF

... have been successfully uploaded. I know they were successful because I got an error my pool_id was not the correct len because I mixed up Pool_Id and web-client id, then the page rendered.

Could it be a problem with my browser not allowing HTTP connects? Or with cloudfront?

from simple-nft-marketplace.

As seen above, it appears that my username is successfully being pulled from the Vue front end, however, my account is not. Im unsure how to solve this problem

from simple-nft-marketplace.

I added this snippet in view to verify my username is being pulled, however when I add the snippet seen below for my account, i get an error:

Login request directly connect to Cognito, not via CloudFront. So that's not a problem. (Both of them are connected via HTTP"S") Additionally, your frontend was rendered correctly. So there is no problem with CloudFront.

Agree

however when I add the snippet seen below for my account, i get an error

The account info is fetched by API Gateway. That means your request was stacked at here. So we should investigate why the API Gateway didn't respond correctly. The simple way to do the investigation is checking the lambda function's log.
getAccount.ts should be invoked by API Gateway when you request your account info. So go to AWS Management Console, find the getAccount function (the name of the function is with random strings which was added by CDK. but the name contains GetAccount prefix.), visit Monitor tab, and click View Logs.

If the log group exists, that means your API Gateway invoked the Lambda function correctly. If not, it was failed. Please paste your raw logs (concealing personal stuff if you need) if your could. Thanks!

Thanks sm for the help!
Here is the log from cloudwatch:

So it seems it cannot connect to AMB, i did enter export AMB_HTTP_ENDPOINT='https://.ethereum.managedblockchain..amazonaws.com' (with my nodes HTTP endpoit)

from simple-nft-marketplace.

Just curious, when you change a file in /provision is there a way to avoid having to run CDK bootstrap and cdk deploy SimpleNftMarketplaceStack again?

Changed the NetworkID accordingly, got the same error:
