Need to ensure that we're referencing importRequest here, not importRequestEntity. Otherwise, the request could be changed between first and second phase of the two-phase protocol

Thanks for adding this in @bbende. Code review looks good, aside from the one note that I made inline about referencing the wrong entity. Still need to do some testing but in terms of the code itself, all is looking good. Will do some testing in the next day or two

[markap14]

Was able to test and all looks good. Given that the only I had was a trivial change, I can make that change and merge if you're good with that @bbende

[bbende]

@markap14 yes that would be great! Really appreciate the review and testing
