Logout 400 Bad Request (Logout URI already defined)

Hi,

I’ve followed the steps to resolve the 400 Bad Request error on logout. However this made no difference. From what I can see my settings are correct but the issue still occurs. What could possibly cause this?

Any help will be greatly appreciated as this is for an urgent project for work.

Thank you in advance.

Regards,
Kostya

It’s hard to tell, but it looks like “Identity” might be capitalized in Okta, but the URI you’re sending has it as lowercase.
