Robot not reciving events #759

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Hi,

I have a super simple robot at "asivansandbx.appspot.com" that isn't 
reciving any event. I am using the latest robot client library. 

In the log I see the following exception:

/_wave/robot/jsonrpc
com.google.gson.JsonParseException: The JsonDeserializer 
com.google.gson.DefaultTypeAdapters$CollectionTypeAdapter@12d26d2 failed 
to deserialized json object {"javaClass":"java.util.ArrayList","list":

I believe that you are testing a robot that was previously using version 1 of 
the 
robots API, and the wave server was sending you the wrong event format. I have 
refreshed our cache so that we should now send you the right event format. 
Please try 
again.

Hi Pamela,
I experience the same error as above with pw-invity@appspot.com, which I 
updated to API v2 as well. Could you refresh the cache for my robot to fix 
this? 
If it's a general problem for people updating their robots from v1 to v2, maybe 
there should be a hint somewhere in the docs about this issue.

Thnaks, Thomas
