Multi tenancy CAP application with custom build tasks fails

[sreehari_vpillai]

Hi ,

I have a CAP project with custom build task( reason is here ) . Now when I add mtx to this project and "cds build" it, it throws this error

package.json has multi-tenancy enabled as well . Any clue ?

=>to fix the errors, I added the below 4 models in the cdsrs.json , and error goes of. service has /-/cds/ endpoints as well . But subscription fails ( with no error I could spot from logs )

"@sap/cds-mtxs/srv/bootstrap", "@sap/cds-mtxs/srv/model-provider", "@sap/cds-mtxs/srv/deployment-service", "@sap/cds-mtxs/db/extensions"

Hi sreehari.vpillai,

I have a similar error:

[cds] - [ERROR] Required CDS models [@sap/cds-mtxs/srv/bootstrap] cannot be resolved. Make sure up-to-date versions of the missing modules are installed.

Could you share your cdsrs.json so I can see how to add @sap/cds-mtxs/srv/bootstrap there?

[sreehari_vpillai]

mioyasutake Hay share your build task and package.json ( hiding any confidential infos ). Perhaps you are missing "@sap/cds-mtxs" in your package.json - make sure you shoot npm install before building the mta.

also in cdsrc.json , for db task , add this model as well "@sap/cds-mtxs/srv/bootstrap" . For nodejs task add this

"@sap/cds-mtxs/srv/bootstrap"

sreehari.vpillai Thanks for your reply. After executing 'npm install' at the project root, the error has gone.

[sreehari_vpillai]

mioyasutake sure. Its a bug I think. I spent some good days on this issue already .

lothar.bender Should we treat it as a bug in cds build ?

Seems that you've also set extensibility: true which requires the model @sap/cds-mtxs/db/extensions. This model defines the extensions table (cds.xt.Extensions) which holds the information of existing extensions.

Extensibility should only be enabled if required - just set it to false otherwise.

If this is not the case, please add the .cdsrc.json and package.json files including the one from the sidecar which is mandatory for Java.

thanks mate. Extensibility is disabled and just adding " "@sap/cds-mtxs/srv/bootstrap" was enough for the custom build tasks to provide necessary mtx endpoints for subscription.

I must say , CAP is a piece of art.
