Netlify Forms with Gridsome/Vuejs - vue.js

Question

So I am trying to process a form request using the netlify forms. Everything works fine except that the data does not get sent with the form.
So here is the form
<template>
<form #submit.prevent="handleSubmit" name="Free Assessment Form" method="post" data-netlify-honeypot="bot-field">
<span class="slogan">{{ slogan }}</span>
<input type="hidden" name="form-name" value="contact" class="hidden"/>
<input #input="ev => formData.business_name = ev.target.value" type="text" name="Business Name" placeholder="Business Name" :class="{'input-error': error}" #change="error = false">
<input #input="ev => formData.first_name = ev.target.value" type="text" name="First Name" placeholder="First Name" :class="{'input-error': error}" #change="error = false">
<input #input="ev => formData.last_name = ev.target.value" type="text" name="Last Name" placeholder="Last Name" :class="{'input-error': error}" #change="error = false">
<input #input="ev => formData.email = ev.target.value" type="email" name="Email" placeholder="Email" :class="{'input-error': error}" #change="error = false">
<input #input="ev => formData.phone = ev.target.value" type="text" name="Phone Number" placeholder="Phone Number" :class="{'input-error': error}" #change="error = false">
<button type="submit" class="form-btn">Submit</button>
</form>
</template>
<script>
export default {
name: 'Form',
props: ['slogan'],
data() {
return {
formData: {},
error: false
}
},
methods: {
encode(data) {
return Object.keys(data)
.map(key => encodeURIComponent(key) + '=' + encodeURIComponent(data[key]))
.join('&')
},
handleSubmit(e) {
fetch('/', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: this.encode({
'form-name': e.target.getAttribute('name'),
...this.formData
}),
})
.then(() => {
this.formData = ""
this.$router.push('/')
alert('Form Submitted!')
})
.catch(error => alert(error))
}
}
}
</script>
Now once the form is submitted I receive my email as expected however, the I only get the form keys. I don't receive the form key values.
In my local developement when I console.log the data passed into the encode method, it is all there so I am not understanding why it is not working.
