412 (Precondition Failed)

[MaxenceIPSSI]

Hello,
I'm a french student working for the first time on a big e-market website and I have a little issue to send my form by mail with EmailJS.
This is my sending code :

"form.current" successfully get my form because when I console.log it, I get what I want to get :

Now there is my template :

As you can see, I get my {{from_name}} value directly from the template, and my {{adresse_un}} value from my form.
I checked again and again my template id, service id and public key and they are all right.

However, I can't send a mail, I have these errors in console :

After some researches about 412 error, I tought understand that could be because of the information I send not matching with what EmailJS is waiting for. But as I explained, for me, everything is fine.

That's why I need your help to make me happy.
Ty for reading !

As you can see, the issue here is the connection to Gmail. You need to allow the permission to "send email on my behalf."
