Biome encountered an unexpected error
This is a bug in Biome, not an error in your code, and we would appreciate it if you could report it to https://github.com/biomejs/biome/issues/ along with the following information to help us fixing the issue.
When opening the issue, please provide a minimal reproduction, or identify and share the file/code that triggers it. Without a way to reproduce the error, the error can't be fixed:

Thread Name: biome::workspace_worker_2
Message: The parser is no longer progressing. Stuck at '{' L_CURLY:96..97
✖ processing panicked: The parser is no longer progressing. Stuck at '{' L_CURLY:96..97
⚠ This diagnostic was derived from an internal Biome error. Potential bug, please report it if necessary.
- Explicitly declaring the
nameattribute, and then runningbiome checkresolves the issue.
<script>
const name = "name";
</script>
<input
type="text"
id="name"
name={name}
required
/>// biome.json
