             Summary: throw not a literal exception in callContext.getArgumentValue when getTypeInference
                 Key: FLINK-26327
                 URL: https://issues.apache.org/jira/browse/FLINK-26327
             Project: Flink

          Components: Table SQL / API
    Affects Versions: 1.14.2

{code:java}
//代码占位符
tableEnvironment.createTemporaryFunction("ROUNDX", RoundX.class);
tableEnvironment.createTemporaryFunction("NVL", Nvl.class);
tableEnvironment.executeSql("select ROUNDX( CAST(1.12345 as decimal(10,3)),NVL(MAX(f0),2) ) from t1").print();

// exception
Exception in thread "main" java.lang.AssertionError: not a literal: NVL($0, 2)

// trace
// `NVL` is a scalarFunction that likes oracle nvl function. And this exception might be thrown from this code in my  `getTypeInference` function of ROUNDX scalarFunction.
Optional<Integer> secondValue = callContext.getArgumentValue(1, Integer.class);{code}
