SIGERROR while sending token

[voteit-top]

Hi :
Tried to send token in nodejs, code is as below:
var tx = await sunWeb.sidechain.transactionBuilder.sendToken(toAddr, 10, '1003606', 'fromAddr') var signedTx = await sunWeb.sidechain.trx.sign(tx) var broastTx = await sunWeb.sidechain.trx.sendRawTransaction(signedTx)
but get SIGERROR:
{
code: 'SIGERROR',
txid: 'badbffe36b7f2136c27f42ca3e4267c7eff0b103fa4d5915521e897992e91580',
message: '....'
}
mainchain is fine. any Idea? thanks.
