Upgrading to 2.4 - Incorrect password at first login attempt results in 404 page on successful entry

[cynthia_lusian]

Scenario in Magento 2.4

1. User is on the log in page and types in their password incorrectly.

2. User receives appropriate error notification and retypes in their password and logs in.

3. User is presented with a 404 page at this URL parameter: /customer/account/loginPost/

4. User is actually logged it but should have been taken to their dashboard: /customer/account/

Why is there a /loginPost parameter in the URL? We tried just hacking it by making a URL rewrite but that had some interesting symptoms....

Any advice is appreciated.

Did you ever get a solution to this issue? I recently upgraded to 2.4.1-p1 and this is happening.
