Stripe.js 2 error

Users can create a Stripe account (their bank details etc because I am building a marketplace) and if they enter their details and try to submit i am getting this error:
Element Button Update all - The service Stripe CUSTOM - Update account DOB just returned an error (HTTP 404). Please consult their documentation to ensure your call is setup properly.

Debug errror:
The service Stripe CUSTOM - Update account DOB just returned an error (HTTP 404). Please consult their documentation to ensure your call is setup properly. Raw error:

{
“error”: {
“message”: “Unrecognized request URL (POST: /v1/accounts/). If you are trying to list objects, remove the trailing slash. If you are trying to retrieve an object, make sure you passed a valid (non-empty) identifier in your code. Please see Stripe Documentation or we can help at Stripe: Help & Support”,
“type”: “invalid_request_error”
}
}

I will attach image of my workflow

Hi @robinrattasep1,

This issue is in the error of the API call:

Try removing the trailing / at the end of your POST request URL
