Why do I get the error "Empty field value even though it is not empty?

Question

I have a problem with my bot... I get the error

RangeError [EMBED_FIELD_NAME]: MessageEmbed field names must be non-empty strings.

}

Even though the fields values are not empty... Can anyone help me? Here is the snippet of code where the error happens:

case 'help':
        let command = interaction.options.getString('cmd', false);
        if(command === null)
            try{
                let embed = new Discord.MessageEmbed()
                    .setTitle('Help')
                    .setColor('ORANGE')
                    .setFooter('Use /help cmd:<command> for more informations on that command!')
                    .addField({ name: 'kill', value: /*'Kills the bot. (Only available to bot-helper role)'*/'hi' }) //line 2081
                    .addField({ name: 'ping', value: 'Get the time delay between when you send the message and when the bot detects it.' })
                    .addField({ name: 'snek', value: 'snek.' })
                    .addField({ name: 'stalk', value: 'Get notified when the user whith the specified id logs in. Only works with this server\'s members.' })
                    .addField({ name: 'oc get', value: 'Get infos about an oc. Needs to have fetched the oc to the database from the message beforehand. See /help cmd:ocmessage.' })
                    .addField({ name: 'oc edit', value: 'Allows for the owner of the oc to edit in the database in case the data is wrong.' })
                    .addField({ name: 'quote', value: 'Starts a quizz about a quote. Guess the character who said that quote!' })
                    .addField({ name: 'fac, flip a coin', value: 'Flips a swiss coin. Warning: There is 1 in 100000000000000000 chance that the piece lands on its side. Be careful!' })
                    .addField({ name: 'hybridgen', value: 'A hybrid generator for you!' })
                    .addField({ name: 'oc message', value: 'Adds a message to the database' })
                    .addField({ name: 'help', valuse: 'Shows this message!' });
                interaction.reply(embed);
            } catch (e) {
                console.warn(e);
            }
    }

I assume you just have to remove name: and value: in each .addField, for example: .addField('snek', 'snek.'), but you will get another error because you are trying to send an embed using interaction.reply(embed), and you have to use interaction.reply({embeds: [embed]}) to make it work
