Post "/rest/v1/[tableName]": unsupported protocol scheme ""

[devhindo]

It shows this error Post "/rest/v1/emails": unsupported protocol scheme "" when deploying from render.com server but it works fine locally. I don't know where the problem is

type Emaildb struct {
	Name    string `json:"name"`
	Subject string `json:"subject"`
	To      string `json:"to"`
	Text    string `json:"text"`
	Date   string `json:"date"`
}

func AddMail(m Emaildb) {
	supabaseUrl := os.Getenv("SUPABASE_URL")
	supabaseKey := os.Getenv("SUPABASE_PRIVATE_KEY_SERVICE_ROLE")
	supabase := supa.CreateClient(supabaseUrl, supabaseKey)

	var results []types.Email

	err := supabase.DB.From("emails").Insert(m).Execute(&results)
	if err != nil {
		fmt.Println("cant insert email to db" + err.Error())
	}

	fmt.Println(results)
}

I think it has something to do with this

I had the same error when I forgot to set my environment variables for the supabase url.
