Traceback when PFS returns non-JSON data #4174
Description
Should perhaps have error handling?
/var/folders/p2/8nvdkp212ys2ct82chgfqzbh0000gn/T/_MEIENBsEE/raiden/network/rpc/client.py:479: UserWarning: Infura does not provide an API to recover the latest used nonce. This may cause the Raiden node to error on restarts.
The error will manifest while there is a pending transaction from a previous execution in the Ethereum's client pool. When Raiden restarts the same transaction with the same nonce will be retried and *rejected*, because the nonce is already used.
Checking if the ethereum node is synchronized
