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?

I was also facing the same issue ..But i am not able to solve the problem...can any one suggest a solution

[christoffer_fuss]

For me this solution is working as well, thank you very much 🙂
I see the books in the fiori application but I have 2 questions:

1. I dont see a HDI container for the subscribed tenant in my Database Explorer.
2. I cannot assign the admin role to use the "Manage Books" app becuase I cannot create the admin role based on the role template "admin". The role is always created with the role template "Extension Admin"

Is this working for you simmaco.ferriero?

Best regards,

Chris

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.

Try setting the HANA Instance's "Allowed connections" option to "Allow all IP addresses" allowall.png. This solved the issue for me but I have to figure out why the "Deny all IP addresses (except Business Technology Platform)" option was throwing an error.

If you have more than one instance running then you have to mention which one to pick up in the subscription handler

[former_member125464]

Hi,

in my case it's already set in this way, so I think that the problem is different.

Simmaco

[former_member125464]

Thanks for your answer, Marc. Here it is the log.

Cosnider that I just cloned the repo and followed those indications, without adding anything else. So, I think you should be able to replicate the same behaviour as well.

Unfortunately the logs point to an issue in a different component: "Caused by: com.sap.cloud.mt.subscription.exceptions.InternalError: Sidecar returned http status 500". Can you please share the logs of the "bookshop-java-public-sidecar" application in your space?

[former_member125464]

Here you go:

I am having a similar issue as well. Subscription fails with srv app giving the logs simlar to the original question.

"c.s.c.m.s.SubscriberSidecarImpl : Sidecar returned http status 500"

and

"Failed to process subscription of tenant '2995b828-ddff-4d9f-ae9b-3df0fafec20a' (service 'MtSubscriptionService$Default', event 'SUBSCRIBE', entity '<no entity>')

However the mtx-sidecar logs says something which goes like "Error: Instance, but no bindings for tenant". I am unable to figure out what does it mean.

I suspect it is failing to create the HDI instance.

mtx-sidecar.txt

[eckart_liemke]

Hi Simmaco,

the error that you see in the mtx-sidecar logs is already an aftereffect of an prior failure.

Could you try to unsubscribe and subscribe again and check in the logs of the mtx-sidecar what the initial error is?

How many databases do you have mapped to your cf space?

Thanks,

Eckart

Hi Eckart,

I have just one database instance on my Trial landscape. I'm attaching here again some new logs.
