Is it easy to find the information you need?

None

Are the instructions clear?

No

How could we improve the Timescale documentation site?

I had some errors when I tried to follow the tutorial.

• Creating a relational database (Step 1)

The command

npx sequelize model:generate --name page_loads \
--attributes userAgent:string,time:date

The output
ERROR: Unable to find models path (/workspaces/vipe-dane-cloud/incubator/hyper-tables/models). Did you run sequelize init?

The fix
First run

npx sequelize init

• Creating a relational database (Step 5)

Missing code.

The fix

// Instantiate a PageLoads object
let pageLoad = PageLoads.build({
  userAgent: "Mozilla/5.0",
  time: new Date(),
  createdAt: new Date(),
  updatedAt: new Date(),
});

// Save the object to the database
pageLoad
  .save()
  .then(() => console.log("PageLoad has been saved successfully."))
  .catch((err) => console.error("Unable to save to the database:", err));

Note createdAt and updatedAt fields.

• Creating a hypertable (Step 3)

The command

npx sequelize db:migrate

The output
ERROR: cannot create a unique index without the column "time" (used in partitioning)

The fix
The error is related to the fact that userAgent is a primary key along with time. Possible fixes are either create a unique index on both time and userAgent or make userAgent not a primary key or partition on both userAgent and time.
