I think the error was thrown in validate phase. I run this test
```java
tester.checkString("json_value(true, 'strict $.foo' default 'empty' on
error)", "empty", "VARCHAR(2000)");
```
which throws exception like this:
```sh
org.apache.calcite.runtime.CalciteContextException: From line 1, column 20 to
line 1, column 23: Cannot apply 'JSON_VALUE_EXPRESSION' to arguments of type
'JSON_VALUE_EXPRESSION(<BOOLEAN>)'. Supported form(s):
'JSON_VALUE_EXPRESSION(<STRING>)'

> Incomplete validation of operands in JSON functions
> -----------------------------------------------------
>
> Key: CALCITE-3243
> URL: https://issues.apache.org/jira/browse/CALCITE-3243
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.20.0
> Reporter: Stamatis Zampetakis
> Priority: Major
>
> The operands of various JSON functions are not validated correctly.
> Consider for instance the {{JSON_VALUE}} function and the following calls:
> {code:sql}
> json_value('{\"foo\":100}', 'strict $.foo')"
> json_value(1, 'strict $.foo')"
> json_value(TRUE, 'strict $.foo')"
> {code}
> The first call is legal but the next are not; if I am not wrong the operands
> should be always CHAR or VARCHAR literals which is not the case above.
> Queries involving such calls fail at runtime when compiling generated code. I
> guess that such kind of problems should be captured by the validator and we
> should not even arrive at the code generation step.
> The problems can be easily reproduced by adding such calls in the
> {{SqlOperatorBaseTest}}.
> The problem does not only affect {{JSON_VALUE}} but other JSON functions
> (such as {{JSON_QUERY}} etc.) as well.
