Android studio Kotlin字符串替换函数不适用于我？

大家好，请帮助我，我试图修改链接，但它不工作。它在java上工作，但最近我将java转换为kotlin并得到了这个错误

我试图用当前登录用户电子邮件更改[USER_ID]中的链接，但出现错误

检查屏幕截图

错误

None of the following functions can be called with the arguments supplied.
CharSequence.replace(Regex, String) defined in kotlin.text
String.replace(String, String, Boolean = ...) defined in kotlin.text

我的代码

  fun modifyOfferLink() {
       val id = mAuth!!.currentUser!!.email
        // Modifying Offer Link Acording to Offer Partner
        when (partner) {
            "ogads" -> Finallink = link + "&aff_sub5=" + mAuth!!.currentUser!!.email
            "offertoro" -> Finallink = link.replace("[USER_ID]", mAuth!!.currentUser!!.email)
            "none" -> {
                Finallink = link!!.replace("[USER_ID]", mAuth!!.currentUser!!.email)
            }
            else -> Finallink = link.replace("[USER_ID]", mAuth!!.currentUser!!.email)
        }
    }
