+Note: making contract calls using Infura fails with `missing trie node` errors. 
+The fix requires editing `ethereum_adapter.rs` line 434 to use the latest block 
+instead of a specific block number. 
+Replace:
+`web3.eth().call(req, Some(block_id)).then(|result| {` 
+with `web3.eth().call(req, Some(BlockNumber::Latest.into())).then(|result| {`

+To run the graph-node with this fix it must be run from source.
+
+First, delete the `graph-node` container from the `docker-compose.yml` file 
+then run `docker-compose up` to get the postgresql and ipfs services running.

+Now you can build and run the graph-node from source
