Fetch transactions from an address
So what did I do so far: I followed this instruction(https://github.com/input-output-hk/cardano-db-sync/blob/master/doc/docker.md) and had a cardano-node, a cardano-db-sync and a postgres isntance running on docker. I was able to successfully connect to the postgres database. However, I was not able to find recent transactions even thought the blockchain was up to date. When I took a close look onto the docker console I saw that the cardano-db-sync_1 process continuously exited with code 126.
