@payal-balanceit Take a look at response.status_description and response.error_description

I've also experienced this problem.

Error's backtrace leads me to the code:
https://github.com/veeqo/ups-ruby/blob/master/lib/ups/builders/organisation_builder.rb#L51
It means organization builder expects attention_name option passed with a non-blank string. It called from add_ship_from and add_ship_to.

@payal-balanceit , as a workaround you can add non-empty attention_name param to add_ship_from and add_ship_to methods

I suppose Veeqo uses these methods with all options filled in production.
