I'm trying to import about 70 visualizations from 6.3.0 to 6.4.0, I've successfully imported to other instances of 6.3 but they're not coming over to 6.4. There are no errors, they just don't import.
If I take a single visualization to test with, I get the message -
Successfully imported 0 objects.
I've looked over the JSON and I don't see any issues but I'm obviously missing something.
All of the associated searches imported successfully and run.
UPDATE: I was able to fix my issue by editing and importing a small number of visualizations at a time and fixing any issues and I go. I'm not sure why that didn't work when importing all of them at one time. It's also very confusing without any errors.
