"verifySignature" function not working in lib/payouts/services.

-- In the documentation, it was written that "postData" should be a string of concatenated values of the request-body object, which should be created by sorting keys in "descending" order, excluding the "signature" key and encryption type should be set to "base64".

-- But in function, it is treating the body as an "object" and converting it using "toString()" then encrypting it in "hex" rather than "base64".

-- code has been fixed and PR has been raised.
