Using above default process the build fails.

PS: Although mongo is installed we are testing with option 1 (psql) during build as per the guide. We have replicated this 5 times and the same error is present on all builds from clean install to the point of error.

Perhaps the version 2.x issue is related to nefertari bug:
ramses-tech/nefertari#130

For reference:

I can confirm that a downgrade to 1.x version of elasticsearch solves the build problem.

That old of a version of elasticsearch is difficult to install on some systems. I tried upgrading versions of requirements but this did not help. I eventually had to hack nefertari_sqla/documents.py file in my virtualenv and change the TYPES_MAP 'string' values to 'text'.
