When no supabaseKey is passed in it throws an error

Chore

Describe the chore

if createClient is called and the supabaseKey passed in is null or undefined then a non-specfic error thrown. This can happen if you make a call like this:

    return createClient(
      process.env.SUPABASE_URL,
      process.env.SUPABASE_PUBLIC_KEY
    );

and the env variable is empty.

The error is:

TypeError: Cannot read property 'length' of undefined

We should add validation that the supabaseKey is passed in or at least fix this line so the error is better handled.
