Unable to subscribe to multi-tenant application

[former_member125464]

Hi,

I've cloned the repository here and I'm following the instruction to use this app as multi-tenant as described in the section "Deploy as Multitenant Application". However after having deployed my app to the Trial landscape, when trying to subscribe from a different subaccount to this app, I receive a "Subscription failed" error. Going deep into the error I see this:

{"subscriptions":[{"subdomain":"e4e45564portal","appName":"bookshop-java-public-e4e45564trial-dev","consumerTenantId":"881d838a-f28e-474f-90c2-c8348f963e98","globalAccountId":"bf4cb67e-7ed3-4154-b699-088e74780602","subaccountId":"881d838a-f28e-474f-90c2-c8348f963e98","state":"SUBSCRIBE_FAILED","error":"subscribe failed.

What could be the problem?

You should find additional information about this error in the logs of your "bookshop-java-public-srv" application (e.g. full Java stracktrace). Can you please provide these logs here to further narrow down the cause of the error?

Hi, just for information. I managed to make it working by changing the package.json file inside the sidecar to this:

{
    "name": "deploy",
    "dependencies": {
        "@sap/cds": "^4.5.3",
        "@sap/cds-mtx": "^1.1.2",
        "@sap/hdi-deploy": "^4.0.3",
        "@sap/instance-manager": "^2.2.0",
        "@sap/xssec": "^3.0.9",
        "@sap/hana-client": "^2.7.23",
        "express": "^4.17.1",
        "passport": "^0.4.1"
    },
    "scripts": {
        "start": "node server.js"
    }
}

and then removing and recreating the subscription.

Not sure if this is the right solution, but worked for me.

Hi Simmaco,

yes, with @sap/cds-mtx@1.1.3, the robustness of the container creation has been slightly improved.
