Square Integration Error: The `Authorization` http header of your request was malformed

Hello, I coming up on this error for one of my forms for payment transactions. I need to fix this asap please
Payment Error

The `Authorization` http header of your request was incorrect or expired. The header value is expected to be of the format "Bearer TOKEN" (without quotation marks), where TOKEN is a valid access token (e.g. "Bearer ABC123def456GHI789jkl0"). For more information, see https://developer.squareup.com/docs/build-basics/using-rest-api#__set-the-headers__ .

kindly re-connect your form to Square first.

You can do so by opening the Square Payment wizard, then changing the mode to Test Mode then back to Live Mode, and finally clicking the Connect button.

Do let us know how it goes for you thereafter.
