[SOLVED] Error when trying to create new document (Function)

Internal error:

TypeScript

Error: Not Found
    at Client.call (/usr/code-start/node_modules/node-appwrite/lib/client.js:171:31)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at async Databases.createDocument (/usr/code-start/node_modules/node-appwrite/lib/services/databases.js:1055:16)
    at async module.exports (/usr/code-start/src/index.js:24:21)
    at async /usr/local/src/server.js:68:13

My function code:

TypeScript

const sdk = require('node-appwrite');

module.exports = async function (req, res) {
  const client = new sdk.Client();

  const endpoint = req.variables['APPWRITE_FUNCTION_ENDPOINT'];
  const project_id = req.variables['APPWRITE_FUNCTION_PROJECT_ID'];

  client.setEndpoint(endpoint).setProject(project_id);

  const operations_collection_id = req.variables['APPWRITE_FUNCTION_OPERATIONS_COLLECTION_ID'];
  const results_collection_id = req.variables['APPWRITE_FUNCTION_RESULTS_COLLECTION_ID'];
  const database_id = req.variables['APPWRITE_FUNCTION_DATABASE_ID'];
  const database = new sdk.Databases(client);

  const { a: value_x, b: value_y } = JSON.parse(req.payload);

  const result = await database.createDocument(database_id, results_collection_id, sdk.ID.unique(), {
    value: value_x + value_y,
  });

  const operation = await database.createDocument(database_id, operations_collection_id, sdk.ID.unique(), {
    value_x,
    value_y,
    result_id: sdk.ID.unique(),
  });

  res.json({
    operationId: operation.$id,
    resultId: result.$id,
    success: true,
  });
};

TL;DR

When trying to create a new document, an "Error: Not Found" message is received. The solution to this error is to include "/v1" for the endpoint. The issue has been resolved by following this solution.
