heroku db:push throws "Taps Server Error: undefined method `symbolize_keys' for nil:NilClass"

I'm in the process of switching to Heroku hosting. I have on my local machine a copy of the current production database (>100 M) and I cannot push it to heroku.

I'm getting the same error over and over again:

Taps Server Error: undefined method `symbolize_keys' for nil:NilClass

This seems to be related to some NULL values in the database (not all). Any ideas on how to fix this? Thanks!

Here is the full output:

Heroku blog has a good discussion on strategies for pushing big data to heroku using taps

  1. To break up the job, push only specific tables
    heroku db:pull --tables logs,tags

  2. Resume transfer using the crash logfile
    heroku db:pull --resume-filename session_file.dat

For more info see: http://blog.heroku.com/archives/2010/4/21/supporting_big_data_part_1/
