cubejs/cube:v0.35.11 results in Model files not found errors

[alyssakelley]

Describe the bug
When we use any version of cubejs/cube past v0.35.10, our cube deployment results in the following errors:

"error": "Error: Model files not found. Please make sure the "model" directory exists and contains model files.",
"stack": "Error: Model files not found. Please make sure the "model" directory exists and contains model files.\n at FileRepository.getFiles (/cube/node_modules/@cubejs-backend/shared/src/FileRepository.ts:31:13)\n at FileRepository.dataSchemaFiles (/cube/node_modules/@cubejs-backend/shared/src/FileRepository.ts:46:19)\n at DataSchemaCompiler.doCompile (/cube/node_modules/@cubejs-backend/schema-compiler/src/compiler/DataSchemaCompiler.js:81:19)\n at CompilerApi.getCompilers (/cube/node_modules/@cubejs-backend/server-core/src/core/CompilerApi.js:67:26)\n at CompilerApi.metaConfig (/cube/node_modules/@cubejs-backend/server-core/src/core/CompilerApi.js:221:23)\n at ApiGateway.load (/cube/node_modules/@cubejs-backend/api-gateway/src/gateway.ts:1597:30)\n at /cube/node_modules/@cubejs-backend/api-gateway/src/gateway.ts:257:7"

We are deploying cube to aks following a similar chart structure as what is documented here: https://github.com/cube-js/cube/tree/master/examples/kubernetes/cluster

To Reproduce
Steps to reproduce the behavior:

1. Use cubejs/cube:v0.35.11 or greater
2. Have cube image deployed with cube.js file in root
3. Port forward cube-api service: kubectl port-forward -n cube svc/cube-api 4000
4. Make a test api call to http://localhost:4000/cubejs-api/v1/load with a valid query parameter included
5. See the error in api output and cube-api pod logs

Expected behavior
Expect the api results to come back with valid data from our ConfigMap that was specified in the query parameter of the call.

Screenshots
If applicable, add screenshots to help explain your problem.

Version:
v0.35.11 through latest does not work

Example cube.js file in root

module.exports = {
    checkAuth: ({ securityContext }, token) => {
      if (token !== null) {
        return;
      }
      
      throw new Error(`Access denied - securityContext: ${securityContext} - token: ${token}`);
    },
    orchestratorOptions: {
      continueWaitTimeout: 15  
    }
  };

@alyssakelley schema path should be updated to be model indeed.

[alyssakelley]

The solution is updating cube.js in the root of the image to be something similar to:

const path = require("path");
const fs = require("fs");

module.exports = {
  checkAuth: ({ securityContext }, token) => {
    if (token !== null) {
      return;
    }
    throw new Error(`Access denied - securityContext: ${securityContext} - token: ${token}`);
  },
  orchestratorOptions: {
    continueWaitTimeout: 15
  },
  repositoryFactory: () => ({
    dataSchemaFiles: async () => {
      const files = await fs.promises.readdir(
        path.join(process.cwd(), "model")
      );
      return await Promise.all(
        files
          .filter((file) => file.endsWith(".js") || file.endsWith(".yaml"))
          .map(async (file) => ({
            fileName: file,
            content: await fs.promises.readFile(
              path.join(process.cwd(), "model", file),
              "utf-8"
            ),
          }))
      );
    },
  })
};

and then making sure the volume mount is updated in the cube-api deployment
