CJA Connection: backfill failure explanation

[liz25]

Hi there, 

When creating a Connection on CJA, enabling backfill of data for my dataset, after processing the backfill I get a backfill status "backfills failed". 

Is it possible to get an error diagnostic for the failure? What could cause a backfill to fail? 

Thanks in advance, 

Liz

Hi Liz,

the best possible place I can think of is going through audit log using [1]
