response = tx.process(true) -->sometimes it gives this error --> undefined method `[]' for nil:NilClass

radiator works good! but sometimes i got a error, see next text code tx = Radiator::Transaction.new(wif: wif_key, chain: :golos, url: 'https://ws.golos.io') tx.operations << transaction_data begin response = tx.process(true) rescue Exception => e puts "forward this message to inertia186/radiator" puts e.message print e.backtrace.join("\n") end

It's a known issue on Golos. The problem can be lessened by picking a more reliable node. But until this is actually fixed in radiator, you can pass an the argument recover_transactions_on_error: false to stop radiator from trying to recover the transaction, .e.g.:

tx = Radiator::Transaction.new(wif: wif_key, chain: :golos, url: 'https://ws.golos.io', recover_transactions_on_error: false)

Keep in mind, often this error means that the node accepted the transaction but could not reply due to timeout. If you re-try the transaction, it could result in a duplicate broadcast. This is especially problematic if the transaction contains a transfer of funds and it is blindly retried after the error.
