What happened?

terraform fails to find route table immediately after creation:

time="2022-07-12T14:52:59Z" level=error

I will open an upstream PR soon.

Note: we are getting lots of route table failures, but they seem subtly different. The error message for this one looks like a failure to read, but terraform resources "read" themselves right after create. So this is a failure of the route table to read itself upon creation--not another resource trying to read the route table, which is a different class of bugs we have.
