Description

Hi Team,

Currently, I am using amplify 2 sandbox to testing my application in local. However, when I ran the command "npx ampx sandbox" it always returned the error "unknown command 'cdk'".

Here is my development environment version:
node: v20.11.1
npm: 10.5.2
cdk (I tried to install it but still had no luck): 2.149.0

Hey @iLoJokerZ, thank you for reaching out. Does the package.json contain the following packages?

"aws-cdk": "^2.148.1",
"aws-cdk-lib": "^2.148.1",
"constructs": "^10.3.0",

was the project was created using npm create amplify@latest?

[iLoJokerZ]

Hi @ykethan. Sure thing. I also tried uninstall and install again.

@iLoJokerZ how is the project currently setup? is this a monorepo?
Could you run npx ampx info and provide us the output?

[iLoJokerZ]

@ykethan, the project tends to build a lambda function, so it was based on the instruction in this link (https://docs.amplify.aws/react/build-a-backend/functions/set-up-function/). Moreover, I also used NestJS as a framework to implement a function.
Here is a information from npx ampx info

Hey @iLoJokerZ, this appears to be an issue with the project setup and not the functions setup.
Is this a windows environment?
Could you provide us a screenshot of the project structure and package.json?
Would you be open for a reach out on discord? my handle is ykethan

Is there any other way besides Discord, because I can't use Discord?

[ykethan]

@iLoJokerZ, just to ensure is this the package.json under the Amplify folder or the root? As did observe the Amplify folder contains node_modules as well.

[iLoJokerZ]

Hi @ykethan, thanks for your suggestion. After I moved the package.json, the issue still there

[ykethan]

Hey @iLoJokerZ, if you are unable to use discord. Could you provide us your email address to setup a call to dive into the issue?

[iLoJokerZ]

Hi @ykethan. My apologize for the late reply. About the issue, it is good now. I am not sure this is a good approach but it helps me solve the issue. I just reinstall my windows, and setup again then everything is good now.

Thank you for your time. We can close this topic.
