Mutt macros can behave strangely if you try to break them into multiple
lines.  So my first suggestion is to try setting your macro to exactly
how it's shown in the tutorial and see if that fixes the problem.  (I
admit that this is not likely your problem though, as notmuch-mutt is
running...)

A more likely idea is to check whether you have $pipe_decode set.
If you have this set, you need to make sure you are not weeding out
message-id with 'ignore'.

In fact, I've just tried this, and I can replicate the problem and exact
error messages with these settings:

  set pipe_decode
  ignore *
  unignore From Date To Cc Bcc Subject

Adding this will fix the problem:
  unignore Message-ID
