I upgraded by cluster to version 7.5 and I'm trying the Transforms from Kibana but I'm having some problem that I cannot identify.
The big picture is that when I create a continuous transform with more than 4-5 aggregations, the transform is created but not the index and it can't be started. When it happens and I click on the "Start" button, the only message I receive is:
"An error occurred starting the transform XXX"
with no further detail...
I've tried creating exactly the same transform (same configuration) and changing the number of aggregations: 1, 2, 3... My final goal is creating one with 13 aggregations but I could never create any transform with more than 4 aggregations.
I also checked that is not a problem with the fields I'm aggregating, because for example, if I create 1 transform with:
It always fails, but if I do 2 transforms with the same aggregations splitted into fields1-2 and fields3-4, then both transforms works normally.
Is there some limitations in the number of transforms supported?
Note: I'm using Elastic Service
Thanks in advance!!!
