+Subject: [PATCH] Filter token data out of catch_errors middleware
+
+If an exception is caught by the catch_errors middleware the entire
+request is dumped into the log including sensitive information like
+tokens. Filter that information before outputting the failed request.
+
+Closes-Bug: #1628031
