"Write here how you think we can improve the tutorial..."

Hi I execute the tutorial and I fail in step 5 with build errors.

Steps I did (to reproduce):

Step I:
Module 1: Prepare for Deployment in the SAP BTP, Cloud Foundry Runtime
https://developers.sap.com/tutorials/prepare-btp-cf.html

Prerequisites
step 1: done

• I used incident-app from https://github.com/cap-js/incidents-app/tree/beginner-tutorials (alternative 2)
  Imported incident-app project into BAS

step 2: ga available, yes
step 3: platform user, yes
step 4: admin ga, yes
step 5: subaccount available, yes
step 6: IAS tenant available,yes
step 7: IAS trust enabled, yes
step 8: web browser available, yes

Module 1 Steps:
Step 1, 2, ..., 5: all done

Deploy in SAP BTP, Cloud Foundry Runtime
https://developers.sap.com/tutorials/deploy-to-cf.html
Step 1: done
Step 2: done
Step 3: done
Step 4: done
Step 5: fails (see full console output in [1])

Step II:
Module 2:
Deploy in SAP BTP, Cloud Foundry Runtime
https://developers.sap.com/tutorials/deploy-to-cf.html

Step 1: done
Step 2: done
Step 3: done
Step 4: done
Step 5: fails with an npm error (see full console output in [1])

The BAS project code I used in this step is published here:
https://github.com/jensglander/full-stack-cap-01/tree/main/incidents-app-clone

Thank you very much for your help to fix this issue.

Best regards,
Jens
