(Anna) #1

Hi All,
I've been using watcher with ES 5.6.3 and after updating to 6.1 the condition code is not working anymore.
Any help will be appreciated
Here is the error I have

Hey,

can you share the full output of the execute watch API? Especially the search response is what I am interested in. It looks as if the aggregations are ignored or cannot be read from the response.

Alternatively a search response from the above query would be super useful as well.

Hi Alex,
Here is the search response and this is the problem, because returns 0 values; thus the watcher is not wrong... my fault :frowning:
I'll take a deeper look into the data and I'll let you know.
Thanks a lot
Ana

Hi Alex,
I found the problem. Somehow I made a cut and paste mistake in the watcher and was pointing to an incorrect index, that why my search result was empty.
In addition I'll add some control to prevent the watcher to throw such an exception when the aggregation is empty
Thank you very much for your time.
Regards
Ana
