es-import-bulk says complete, but 0 object count in AWS ES

Hey there,

I am trying to use these tools, as they are much faster than elasticdump (thanks a lot for that!!), but I am having this weird issue:
It seems that I can import the mappings correctly:
es-import-mappings --url <MyESDomain>/ --file index_mappings.json

Creating Indexes (if needed):
[index="userupdates_v1"] - creating
[index="users_v1"] - creating
Creating mappings:
[index="userupdates_v1", prop="userupdate"]
[index="users_v1", prop="user"]
Done!

Which I can only verify by viewing them in the AWS console

Next, I am importing the userupdates_v1 index, by:
$ es-import-bulk --url <MyESDomain>/ --file index_userupdates.json

Pre-Processing file of size: 9.18 MB
Starting bulk imports with batches of 20000 lines.
Processing line 70240 of 70240 [====================] 100% 16.0s
Complete!

But by going again to the console, the count is still 0

(I have also tried with /userupdates_v1 suffix on the ES domain, but still getting the same result)

Biggest issue here is that there is no verbose or debugging mode for the es-import-bulk tool, so there's no way of knowing what's the issue.

It was eventually due to a type mismatch issue in the indices. This should be outputted as an error.
