Not able to create valid signature using getSignatures method

[untitledlt]

I am trying to create an unsigned transaction using @bsv/sdk lib and later sign it using Yours wallet.
No matter how I try, I am not able to produce valid signature to unlock utxo.
I tried doing this on testnet and mainnet.
Here's the parsed signature from whatsonchain.com (note [error] at the end):

"scriptSig": {
  "asm": "45022100b4a4cd3da500c325f445ea3eae25c1365a7a59f1501ab51a78dca27f5841e7d602202ae8e1680a295d7247fe OP_UNKNOWN197 OP_UNKNOWN208 OP_BASE OP_0NOTEQUAL OP_UNKNOWN240 OP_14 OP_UNKNOWN239 OP_UNKNOWN243 OP_UNKNOWN246 OP_ROLL OP_16 [error]",
  "hex": "3045022100b4a4cd3da500c325f445ea3eae25c1365a7a59f1501ab51a78dca27f5841e7d602202ae8e1680a295d7247fec5d05092f05eeff3f67a6045d9493dd032a8fc90c1fd41",
  "isTruncated": false
            },

I have created a minimal React project to show how I do that:

Please guide me what I am doing wrong here. Thanks!
