Serverless CORS Issue

Hi,
 
I'm getting a CORS error for trying to call my hubspot hosted serverless function from my hosted hubspot website page:

 

'Access to fetch at https://mabletherapy.com/_hcms/api/submitResponses' from origin ' https://www.mabletherapy.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. 

 

I'm using the same protocol and therefore should not be getting this error according to your docs:  
https://developers.hubspot.com/docs/cms/data/serverless-functions/reference#cors
 
{
"runtime": "nodejs18.x",
"version": "1.0",
"endpoints": {
"submitResponses": {
"method": "POST",
"file": "submitResponses.js"
},
"submitContactForm": {
"method": "POST",
"file": "submitContactForm.js"
}
}
}
 
My headers for my api calls are as follows:

headers: {
  "Content-Type": "application/json",
  "Access-Control-Allow-Origin": "*"
}


Is there a way to get around this error?

Serverless CORS Issue

Hi Bérangère,

 

Thank you for sharing those articles. After reviewing them thoroughly, I found that none of them are relevant to my issue.

 

Could you please provide some development support on this?

 

P.s. I have added the domain www.mabletherapy.com over to the advanced tracking under settings.
