[c5291887]

Hi Colleagues,

We are testing Starter Scenario for September month cycle in US region.

Tutorial link: https://developers.sap.com/tutorials/cap-service-deploy.html
Trial account link: https://cockpit.hanatrial.ondemand.com/trial/#/home/trial

Here in step no 3, deploy using CF deploy, this command "mbt build -t gen --mtar mta.tar" is giving error as below.

" [2024-09-12 14:40:04] ERROR could not build the MTA project: could not execute the "make -f Makefile_20240912143957.mta p=cf mtar=mta.tar strict=true mode= t="gen"" command: exit status 2
Error: could not build the MTA project: could not execute the "make -f Makefile_20240912143957.mta p=cf mtar=mta.tar strict=true mode= t="gen"" command: exit status 2"

Please find the attached screen shot for reference.

Hi @c5291887 ,

you're using Powershell. Could you please test it with another CLI?

[c5291887]

Hi Rene
we have verified in git bash and cmd but still the same error exists. kindly help us to proceed further.

[renejeglinsky]

As this is a different error and you closed the issue, I assume you executed the tutorial successfully. Thanks for testing and reaching out :)

[renejeglinsky]

For the current error, you need to create a DB, according to the error message.

[c5291887]

Hi Rene
Yesterday i did some work around n got some different error.
But now i executed same scenario from scratch and got same error in Git Bash also. Kindly suggest me to proceed further. Thanks for your support.

There seems to be a problem with the nmp ci command. Could you attach the whole error log? I'm not sure what causes this upstream conflict. I haven't seen this before

[renejeglinsky]

And please provide the versions you're using: cds v -i

[c5291887]

Hi Rene,

[renejeglinsky]

Please do cds v -i inside the my-bookshop project. I'm pretty sure you'll find @sap/cds with 8.1 or less there. I could reproduce your error when using @sap/[email protected] and at the same time using @cap-js/[email protected]. You log in the terminal (was not part of your screenshot) contains:

Error: npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: [email protected]
npm ERR! Found: @sap/[email protected]
npm ERR! node_modules/@sap/cds
npm ERR!   @sap/cds@"8.1" from the root project

npm ERR! Fix the upstream dependency conflict, or retry

Solution:
You dependencies in your package.json should look as follows:

"dependencies": {
    "@sap/cds": "^8",
    "express": "^4",
    "@sap/xssec": "^4",
    "@cap-js/hana": "^1"
  },

After npm install you should find @sap/[email protected] when doing cds v -i. And then also the MBT build works.

[c5291887]

We are able to create mta.tar file with cds version "@sap/cds": "^8" and while deploying i got this below error.

Creating service "my-bookshop-db" from MTA resource "my-bookshop-db"...
Error monitoring creation or update of services: Error creating service "my-bookshop-db" from offering "hana" and plan "hdi-shared": Service broker error: Service broker hana-broker failed with: Can not create service instance 'my-bookshop-db': There is no database available. Ensure that you have a database available in space 'dev' within organization 'd5e66d9btrial'.

[c5291887]

Am able to create database instance manually but from vs code its not happening "cf deploy gen/mta.tar".

The instance "abc1234" which we created manually.

Kindly suggest me to proceed further. Thanks

[renejeglinsky]

Hi,
I can't reproduce this. For me it works.

Please delete all service instances and apps related to this tutorial and make a fresh deployment. I'm sure it will work then if the DB is running.

[renejeglinsky]

@c5291887 Can you confirm it worked?

[c5291887]

Hi Rene,
Yesterday i retested the scenario with new instance creation and deployed successfully and log file is generated as per the requirement.

The URL generated in log file is not launching as per requirnment.

Kindly suggest me to proceed further. Thanks

[renejeglinsky]

Please use the other URL from the AppRouter (the one without -srv):

Application "my-bookshop" started and available ...

[c5291887]

I have launched this URL "fb2f4044trial-dev-my-bookshop.cfapps.us10-001.hana.ondemand.com" in different browsers and i got below response.
