Hey guys,

first of all, you have created a very nice product. Thank you very much :slight_smile:

I want to have a contact form on my website, which pushs entries into my Strapi collection. It works fine with Postman but with my Nuxtjs application not.
The first entry can be added via my Nuxtjs application, all fine. If I want to send the contact form again, nothing happens. In Postman, I can send it many times and all works fine.
I tested the Nuxtjs application on localhost and Vercel. Same issues on Vercel.

My contact form:

data() {
return {
firstName: β€˜β€™,
methods: {
async addLead () {
try {
await this.$strapi.create(β€˜leads’, { firstName: this.firstName })
} catch (error) {
this.error = error;

It would be Great, of you Can help me out here.

Best regards
