Hi,
I am trying to test a transaction model where given a valid testnet bitcoin cash address I a transfer funds from one address to another. I am able to fetch the UTXO's and I am able to create a raw transaction successfully using 'createrawtransaction' RPC. However, I feel like there is something wrong that is going on while I am signing the raw transaction using the 'signrawtransaction' RPC. There are no errors and I am also able to send the raw transaction but its not getting mined. So I tried to broadcast the transaction through 'https://test-bch-insight.bitpay.com/' and it returned an error saying
"An error occurred: 16: mandatory-script-verify-flag-failed (Signature must be zero for failed CHECK(MULTI)SIG operation). Code:-26"
Then the next step I took is to create the transaction using bitcoincashjs and compare the raw transaction after signature. There seems to be a difference in script signature for both of the raw transactions.

In testing this I have used the same address with same amounts for the transaction. I have used the bcash 'decoderawtransaction' to decode both the raw transactions. The signed raw transaction by bitcoincashjs is able to also mine.
FYI: I have used bcoin to create the same model for bitcoin and that works fantastic.
Kindly request the developers to through some light.
Thank you for your help in advance.
