TypeError: field.childNamed is not a function

Hi,

We are trying to create a changeset by doing a diff on two branches.

git diff develop feature/marketing | force-dev-tool changeset create mkt_diff

when I do that, I get an error. Here's the stack trace.

exported metadata container to config/deployments/mkt_diff

Forgive me if this is elementary, we're a little new to this. We installed the tool using npm install this morning, so we believe this is the latest version.

Thanks in advance!

To add to this, we have identified that this only occurs when we include Opportunity and Contact workflows.

@BobHatcher Thanks for reporting!
I just fixed this on the master branch.
Please install force-dev-tool using npm install git+https://github.com/amtrack/force-dev-tool.git until a new release has been published.
