VS Code SAPUI5 Adaptation project error - Request failed with status code 401

[ScottZheng]

When I create the SAPUI5 Adaptation project, I got the error: Request failed with status code 401

I checked my SAP system setting, it's working fine for connection of SAP backend system.

I turned on Trace mode for extension Application Wizard in VS Code to track the log when I process the same above-mentioned steps.

In the output screen, it showed error

My error message is like below:

2024-05-08T08:18:44.267Z [ADP Creation] [INFO] : Response status = 401

2024-05-08T08:18:44.267Z [ADP Creation] [INFO] : END - system response error result.

2024-05-08T08:18:44.269Z [ADP Creation] [INFO] : AxiosError: Request failed with status code 401

Compared to the log from my colleague with no such issue, he got bellow log message. For the 404 error, it should not be a problem, because he didn't select the version. In his case, the system connection is fine from his side by using SAPUI5 Adaptation project.

I also checked with authorization colleague, and my SAP account got no authorization issue for system connection. It might be something wrong for my local setting. Does anyone can help me with this issue?

Thanks in advance.

Hi Scott,
I had the same problem as you and I managed to solve it.

Running the command

C:\Windows\System32> npm install -g @Sap/generator-adaptation-project 

I received this response:

npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.

once I updated nodejs to version 18 I was able to install the latest version of the generator @Sap/generator-adaptation-project

If I now run this command 

C:\Users\username>npm list

I get this response

username@ C:\Users\username
`-- @Sap/generator-adaptation-project@1.1.58

I didn't understand why in "Explore and Install Generators" I still see version 1.1.40 but now it works...

https://www.npmjs.com/package/@sap/generator-adaptation-project/v/1.1.58

I hope will help you.
