            interaction.reply({embeds:[new1]})



         




    }
}

So this is my code the temp,lan,lat variables were number but i changed them into string and even checked with the typeof method It gave me a string

But still i'm facing out this error called RangeError [EMBED_FIELD_NAME]: MessageEmbed field names must be non-empty string

Please help me if you know whats the solution
