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.

are you able to connect to abap system from ADT with your account?

This is a fiori application generator version issue run below command and it will solve this issue

npm install -g @Sap/generator-fiori@latest

you can check the version on 'i' button.

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:

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.

Moreno

Hi Moreno, thanks for sharing. I followed your instruction, updated node.js to the latest version and used command 

npm install -g @Sap/generator-adaptation-project. Once I tried to create adaptation project, I still get the same 401 error.

[ScottZheng]

Hi Sushaku, thanks for your information. But maybe it's not for my case, because what I am using is Adaptation Project not SAP Fiori Application generator

[ScottZheng]

Hi Jun, I tried in ADT, it works. fine.

[ScottZheng]

But VS code is still not working

[junwu]

save the system with your account/pwd in your colleague's computer and try to create adaptation project. if it works, that means your account is good, and you have to check your local environment( maybe node js version). if it didn't work, probably your account has some issue.

[ScottZheng]

Hi Jun, I did the other way around, I used the account from my colleague who has no issue to setup the system. And it still causes 401 issue. It seems like, it's not the SAP authorization issue. I also used another PC for installing all stuff with the newest version, still got 401 error ;(

Scott - Were you able to go past this 401 issue?I am getting the same issue. And after few tries, Wizard closes itself without going to system selection step.

[ScottZheng]

Still got 401 error, and didn't find the solution yet

This is a fiori application generator version issue run below command and it will solve this issue
