@maminebnr were you able to fix this? any update or workaround as I'm facing same issue after generating private key using BitPaySetup script from their nodejs sdk, and token is paired to dashboard

bitauth.sign(data,key) returns an array

convert the array to hex string
bitauth.sign(data,key).toString("hex")
