jmeter if控制器表达式怎么引用用户参数做判断

想通过线程组下某一个用户参数做判断条件，但是一直提示异常，如果该参数换成用户定义的变量，或者json提取器提取的变量或者vars.put()声明的变量则都可以引用，唯有用户参数中定义的就报异常，jmeter版本5.4.1，有谁知道原因指点一下吗？
以下几种写法都不行，而且也试了勾选和不勾选Interpret Condition as Variable Expression

${age1}==20
${age1}=="20"
${__groovy(${age1}==20,)}
${__jexl3(${age1}!=20,)}

异常日志：__groovy

Possible solutions: is(java.lang.Object), any(), get(java.lang.String), use([Ljava.lang.Object;), any(groovy.lang.Closure), tap(groovy.lang.Closure)

最后一张图，不勾选Interpret Condition试试。
