Handle response - SyntaxError: Unexpected end of input when using mode: 'no-cors'

Question

I tried a ReactJS fetch call to a REST-API and want to handle the response. The call works, i get a response, which i can see in Chrome Dev Tools:

function g         


        

Answer 1

I know this answer might be super late and might have been resolved but i just had the same issue today and I just needed to add a ',' at the end of the headers hash and i stopped getting the error

export function addContacts(formData) {
  return(dispatch) => {
    dispatch({type: 'POSTING_CONTACTS'});
    console.log(formData)
    return fetch(uri, {
      method: 'POST',
      body: JSON.stringify({contact: {name: formData.name, phone_number: formData.phoneNumber}}),
      headers: {
        Accept: 'application/json',
        'Content-Type': 'application/json'
      },
    })
    .then(response => {
        return response.json()
      }).then(responseJSON => {
        console.log(responseJSON)
        return dispatch({type: 'ADD_CONTACT', payload: responseJSON});
      })
  }
}
