401 - Application Backend - SAP Build Apps

[erickgomez-tech]

Hi,

When you get the data from the newly created and deployed backend, you get an error that says: "Failed to load data." and if you try to add a record you get a 401 error - permissions.

Reading the forum I have seen that others have had the same problem, some as recent as me.

If anyone else already solved it, I would appreciate the help.

Kind regards.

Is this Std or Custom Odata service?

Hi @Summitt12 

Custom 🙂

Best regards,

First check connectivity with a Std OData Service

Are you using embded or Hub Gateway?

The problem only occurs with the Backend created in SAP Build Apps, called Cloud Functions.

The error is a permission error, I am missing 2 permissions according to the guide, I tried with 2 different users and the problem persists.

The thing is strange 🙂

I had similar issue, with additional "403 Forbidden" while accessing the entity from an app - the quick, but dirty solution in my case was to remove all the roles and all the users from my backend. It seems to me like there is an issue with roles and permissions.

Hi @Jakub_Roguski 

I had the 403 error when I just activated the Standard plan of SAP Build Apps, I was on the Free plan.

With that resolved, I can make Apps, I can create Backend and everything is fine until I try to view or add data.

That 401 error is authorization, I already have them assigned and it still fails, I'm going to do what you mentioned, remove roles and assign them again, I'll give you feedback.

Thanks for the support.

Hello Erick,

Recently SAP implemented Roles and Authorizations for the Visual Cloud Functions backend. These Roles have nothing to do with the Role Collections in BTP Cockpit. 

Please follow the below steps in the same sequence:

1. Create the Entity 

2. Create a Role - under Roles tab. 

3. Then Complete the Deployment. 

4. Then go to Users tab and assign the Role to your email id. 

Here is the documentation https://help.sap.com/docs/build-apps/service-guide/roles

Thanks,

Hi @Venkat_Vyza 

I don't see where the answer can be marked as a solution, do you know where?

[Venkat_Vyza]

This is interesting. Now there is no way that the person who asked the question can mark the correct answer. Maybe the moderators will do that, not sure though!

Each area of the community can have discussions or Q&A, and only Q&A can be marked as solved. I will push for this area to implement Q&A instead of Discussions.
