**Error** from the compiler, while it builds your `.tsrx` files.

## What happened

Markless prints the message, the reason, and a suggestion:

```text
MARKLESS_COMPONENT_BARREL_UNRESOLVED: MARKLESS_COMPONENT_BARREL_UNRESOLVED: <filename> re-exports <exportName> from <source>, which does not resolve to a module.
A barrel names the parts module rather than the components, so a re-export that resolves to nothing would silently drop every component behind it.
Check that <source> exists next to <filename> and is reachable by this build's resolver.

```

Words in angle brackets change from case to case.

## How to fix it

Start with the suggestion in the message above.
