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

## What happened

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

```text
MARKLESS_STATE_MODULE_ESCAPE: Cannot write to "<target>"<aliasText>.
Module-scope storage outlives a single server render. A handler could read or overwrite data from another user because the value is not part of this document payload.
Keep per-document values inside state(), or use shared() for named request/container/page dataflow instead of module variables.

```

Words in angle brackets change from case to case.

## How to fix it

Start with the suggestion in the message above.
