Two attempts to upload a CL to gerrit failed with "Error after CL description prompt".  The CL was created on gerrit, but the link between that CL and my checkout doesn't exist ("git cl try" says to upload first).  

The CL created from the first attempt was https://chromium-review.googlesource.com/c/chromium/src/+/665586, which I abandoned to create a new one.  The second CL created is https://chromium-review.googlesource.com/#/c/chromium/src/+/666997.

The output from git cl upload and git cl try from the most recent attempt follows; let me know what debugging information you'd like from the checkout.
