Error message

networkAllowlist[${index}] must use an exact hostname; wildcards are not supported.

What it means

The parsed allowlist hostname is '*', or starts with '*.' — the sandbox proxy only supports exact hostname matches, no wildcards.

Solutions

1. Use an exact hostname in networkAllowlist[${index}]; remove wildcard patterns.
