Invalid Hash error - Githubissues

I copied the code from this repo and tested it in my app with my prod key-salt and test key-salt. But it returns an Invalid hash error after creating the hash inside override fun generateHash().

`private fun preparePayUBizParams(): PayUPaymentParams {

    val vasForMobileSdkHash = HashGenerationUtils.generateHashFromSDK(
        "$prodKey|${PayUCheckoutProConstants.CP_VAS_FOR_MOBILE_SDK}|${PayUCheckoutProConstants.CP_DEFAULT}|",
        prodSalt
    )

    val paymentRelatedDetailsHash = HashGenerationUtils.generateHashFromSDK(
        "$prodKey|${PayUCheckoutProConstants.CP_PAYMENT_RELATED_DETAILS_FOR_MOBILE_SDK}|",
        prodSalt
    )

    val additionalParamsMap: HashMap<String, Any?> = HashMap()

    additionalParamsMap[PayUCheckoutProConstants.CP_VAS_FOR_MOBILE_SDK] = vasForMobileSdkHash
    additionalParamsMap[PayUCheckoutProConstants.CP_PAYMENT_RELATED_DETAILS_FOR_MOBILE_SDK] =
        paymentRelatedDetailsHash

    return PayUPaymentParams.Builder().setAmount("10.0")
        .setIsProduction(false)
        .setKey(prodKey)
        .setProductInfo("Testing")
        .setPhone(phone)
        .setTransactionId(System.currentTimeMillis().toString())
        .setFirstName("Gulsher")
        .setEmail(email)
        .setSurl(surl)
        .setFurl(furl)
        .setAdditionalParams(additionalParamsMap)
        .setUserToken("Happy69")
        .build()
}`

And
