[Solved] Invalid contract value: xdc gets appended instead of 0x

The contract address in my code is "0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266".

It still says its the same issue.
index.ts:213 Uncaught (in promise) Error: invalid BigNumber string (argument="value", value="xdcf39fd6e51aad88f6f4ce6ab8827279cfffb92266", code=INVALID_ARGUMENT, version=bignumber/5.4.1)
