Huzzah esp8266 crash when subscribing to group without specified feed #120

Closed phord closed 4 years ago

phord commented 4 years ago

Huzzah board crashes if I try to subscribe to a group without providing a feedname. For example, I changed this line in adafruitio_12_group_sub.ino:

-  group->onMessage("count-2", two);
+  group->onMessage(two);

When run, the app crashes. It works if I subscribe to individual feeds by name, though.
