Solutions

1. Fix the condition reported by the error: Error starting measurements for event set {}: {}
2. Check the throwing call site and ensure its documented preconditions (argument values, types, environment, or configuration) are satisfied before the call.

Example fix

Validate inputs and environment so that the failing condition does not occur: Error starting measurements for event set {}: {}

When it happens

Trigger: Thrown at compiler/src/org.graalvm.papibridge/src/papibridge.c:128 when the library encounters an invalid state.

Common situations: Occurs when a caller violates the contract guarded by this check: Error starting measurements for event set {}: {}
