Good evening, I have an error and I don’t know why. “name with value “[object Object]” must be of type string” must be of type string

This is the variable (GRUPO_PERSONAS_ID)

const GRUPO_PERSONAS_ID = 'my-unique-person-group'

 console.log('-----------------------------------------');
 console.log('Person group');

await client.personGroup.create(GRUPO_PERSONAS_ID, {
            'name': GRUPO_PERSONAS_ID
        })
        .then(() => {

        }) 
        .catch((err) => {
            console.log(err)
            throw err
        })

The previous code is the only one that I use, in fact I do not understand but it generates the following error:
