SQLITE_ERROR: no such table: localized_AdminService_Authors

[jbm1991]

Hi, in an attempt to learn about the authentication and authorisation in CAP apps on Cloud Foundry I have been using this documentation https://cap.cloud.sap/docs/node.js/authentication.

In summary, I have run through the https://cap.cloud.sap/docs/get-started/in-a-nutshell guide in the CAP documentation, followed by the "Token-Based Authentication (JWT)" section in the authentication documentation I linked to above, all the way through to the final step just before the "Custom Authentication Middleware" section.

When I am running my CAP service to test it, in an incognito window, I am made to log in as expected, but then when I try and access my Admin service which is protected by the admin role I receive the following error.

GET /admin/Authors
[2020-08-10T07:47:48.189Z | ERROR | 1431319]: SQLITE_ERROR: no such table: localized_AdminService_Authors
[2020-08-10T07:47:48.189Z | ERROR | 1431319]: Error stacktrace: Error: SQLITE_ERROR: no such table: localized_AdminService_Authors

I have tried a few things I found in other answers which sounded similar however none of those have worked. Any help would be much appreciated. I have included file I think may be relevant below.

Hi John,

Did you deploy your database artifacts?

-> cds deploy --to sqlite

Alternatively, you can run

-> cds watch
to automatically redeploy and restart on file changes.

Best regards,
David

Thanks for the quick reply david.kunz2

cds watch is how I'm currently running the data service already, however I have tried your other suggestion, but that hasn't made any difference unfortunately.

I think an extension to my original question might be, why is it asking for/trying to use localized tables only after I added authentication? If I remove the "requires:'admin'" from the admin service then it returns the data correctly

Hi John,
This is indeed a strange behavior. Which version of @sap/cds are you using?

cds -v

Did you try with the latest one (4.1.5)

[jbm1991]

Hi John,

Can you please share your project so we can reproduce?

Thanks and best regards,

Hi John,

I had the exact same issue, and it took me a couple of time to figure out the solution, though, I am not sure what was the reason.

I was using BAS, and what I had to do was to cds deploy --to sqlite again and then re-start the service.

Before, I had the issue with CDS watch returning "Cannot find module 'sqlite3'", so I had to do the following to get at least the metadata displayed:

• In root folder of application (e.g. bookshop/): npm install
• Afterwardds, for all terminals: unset NODE_PATH
• Afterwards: cds deploy --to sqlite

Maybe somebody from SAP could enlighten us what went wrong. I just followed the instructions from here:

https://open.sap.com/courses/cp7/items/5QKEq8Yz5ZcCticDU8KGAz

as shown by johannesvogel

Best regards,

Aleks

Hi I know this is an old post but I am currently doing this same training project and I have the same issue. I'm surprised there isn't a more definitive solution 4 years later but I got it to work.

I have had this problem before on other frameworks and the problem lies in the package-lock.json file. Delete that file, do an 'npm install' and redeploy with 'cds deploy'. That should refresh the package-lock file and update it and work.

Hi John,

I've encountered the same issue after updating my schema.

To solve it, I've recreate/redeploy to the SQLite dev. Other script was inserted in package.json

{
...,
"scripts": {
    "start": "npx cds run",
    "dev":"npx cds watch",
    "dev:db-sync": "cds deploy --to sqlite:raprincis.db",
    "dev:db-deploy": "npx sqlite3 raprincis.db .dump && sqlite3 raprincis.db .tables",
    "dev:db": "npm run dev:db-sync && npm run dev:db-deploy"
  },
  "cds": {
    "requires": {
      "db": {
        "kind": "sqlite",
        "credentials": {
          "database": "raprincis.db"
        }
      }
    }
  }
}

And at the end I run:

npm run dev:db
