I have ressolved the issue.

Solution:

I was using bech32 address, So all I needed to do was to append "01" or it's defined constant "SIGHASH_ALL" to the end of the signature

"signatures":["304502210092f180db9348d8ba99d76628a61b43fe5ab0d5797334670615c1e1cd9ad9799e022049227e343174dfaa5ff215955128a0b23255c59b284268ee22a520d52162bd6601"]

If you are using a bech32 address (starting with bc1) be sure to add "01 (SIGHASH_ALL) " at the end of the signature.

BEFORE ( ERROR: didn't add "01" to the end of the signatures array value(s) ) "signatures": [ "3045022100c7449a84b76dbcef176be03d26d295962f8c06044106dbfc33280b0f0e9a275e02202124b5949b9c379cec05e0facb65d9e0c52b56987939dd736c12fd80a9986086" ],

AFTER ( SOLUTION : adding "01" to the end of the signatures array value(s) ) "signatures": [ "3045022100c7449a84b76dbcef176be03d26d295962f8c06044106dbfc33280b0f0e9a275e02202124b5949b9c379cec05e0facb65d9e0c52b56987939dd736c12fd80a998608601" ],

@skullpunks is your issue resolved? I'm facing the same issue, have added 01 at the end of the signature but still facing the same issue?
