+### Catching Failed Reads and Writes
+Errors in reads and writes can be caught using the node-red `catch` node as usual.
+Standard error information is availlable in the default `msg.error` field; additional
+information about the underlying error is in the `msg.influx_error` field. Currently,
+this includes the HTTP status code returned from the influxdb server. The `influx-read`
+node will always throw a `503`, whereas the write nodes will include other status codes as detailed in the [Influx API documentation](https://docs.influxdata.com/influxdb/v1.7/tools/api/#status-codes-and-responses-2).
