facing issue of invalid signature when sending delegate transaction. (Error: couldn't issue tx: flow check failed: failed to verify transfer: invalid signature)

[Aayush3Intervision]

I am trying to use script of delegate transaction from example of p-chain while doing this I am getting Error: couldn't issue tx: flow check failed: failed to verify transfer: invalid signature Here is my .env file

AVAX_PUBLIC_URL="https://api.avax-test.network/" PRIVATE_KEY=0x........ C_CHAIN_ADDRESS=C-fuji12xejcj3g9748wr8x7qrlqqntemnznx6xam44dt X_CHAIN_ADDRESS=X-fuji12xejcj3g9748wr8x7qrlqqntemnznx6xam44dt P_CHAIN_ADDRESS=P-fuji12xejcj3g9748wr8x7qrlqqntemnznx6xam44dt CORETH_ADDRESS=0xAa95D3C6542eB8FFf583ef0368a6f522e0c157c5 NODE_ID=NodeID-Drq7Ntpsewpdd6RtegNPtH98RZz7ioyYX

Here is the code for that ` const { avm, pvm, evm, Context, utils, networkIDs, addTxSignatures, secp256k1 } = require('@avalabs/avalanchejs'); const dotenv = require('dotenv'); const path = require('path'); // const winston = require('winston'); // Logging library
