This is a direct consequence of bug 1653050, and there's not much we can do, short of taskcluster providing a way to get older tasks for a given index.

I updated to 2dd0d0b26390 and bootstrapping is working now.

Thanks for the report!
Unsure what the ideal solution is here - the new revision depends on artifacts built from that new revision, so there's going to be a window of unavailable artifacts either way.
However, the error message here can be improved to include the workarounds:

• Wait a bit (an hour, tops, IIRC) then try to bootstrap.
• Check out an older revision and bootstrap.

The problem is "an older revision" might be really old, because this will happen when a toolchain is rebuilt (with the same index) for some reason (like docker images being rebuilt), and that's when it's really a problem (because in the more normal case, it would only happen for people who check out autoland).
