Internal Error
Q-0-1 — Internal Error
An error condition that points at a bug in Quarto itself.
What this means
Q-0-1 is the catalog’s sentinel for errors that should not
occur during normal operation. The condition was reached by a
code path Quarto did not expect to reach — an invariant
violated, a defensive unreachable! taken, a state machine
that landed in an unexpected branch.
If you are seeing it, you have most likely found a bug.
Why this happens
The trigger varies — by definition, Q-0-1 is what Quarto
emits when it does not have a more specific code that fits.
The accompanying message names the immediate condition; the
context (the document, the configuration, the command line)
is what reproduces it.
How to fix
Report the failure at the Quarto issue tracker. The most useful report includes:
- The Quarto version (
quarto --version). - The command you ran.
- The full error output.
- A minimal reproducer, if you can construct one.
If the error blocks work you need to ship, you may be able to find a workaround by changing the input that triggers it (a different output format, a different configuration option). The workaround does not fix the underlying problem but can unblock you while the bug is investigated.
