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

## What happened

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

```text
MARKLESS_STATE_REST_ALIAS_EXCLUDED_PATH: Cannot write to "<source>" because "<excludedPathSource>" was excluded when "<aliasName>" was created.
Object rest destructuring creates an alias for the remaining graph paths only. Paths explicitly destructured out of the source object are not owned by the rest alias.
Write through the original graph path, or use the explicit destructured alias for the excluded property.

```

Words in angle brackets change from case to case.

## How to fix it

Start with the suggestion in the message above.
