Fix IllegalStateException

in Nx

Solution

The "IllegalStateException" in nx often arises from duplicate task registrations within your nx.json or project configurations, such as defining the same target with identical executors multiple times. To resolve this, carefully review your nx.json, project.json (or equivalent config files), and any plugin configurations for redundant entries; remove any duplicate task definitions or consolidate them into a single, correctly configured target.
