groovy.json.JsonException：无法确定当前字符，它不是z/OS上的字符串、数字、数组或对象（groovy-2.4.12）

我试图在Groovy中运行RESTClient，使用下面的代码执行HTTP PUT请求，但是我面临一个问题

def jsonObj = JsonOutput.toJson(version)
println(jsonObj)
def jsonObjtrim = jsonObj.trim()
println("**** FIND 1ST CHAR *******")
println((int)jsonObjtrim.charAt(0))
def response = client.put(path: "/cli/snapshot/createSnapshot",
            contentType: "application/json",
            body: "$jsonObjtrim",
            headers: [Accept: 'application/json'])
println("JSON value is $jsonObj")

在构造JSON之后，我让上面的代码打印JSON值，以确保传递的值正确，并且可以在下面的输出中看到。在下面打印的错误中，第一行是我构造的JSON，第三行确认JSON对象的第一个字符是{，因为根据日志，这就是错误所在

输出日志

{"name":"RESTSnapshot3","application":"JKEBank","description":"Requesting deployment","versions":[{"Mortgage":"448.20170828-1755250845"},{"Mortgage":"845.20190507-1820230086"}]}

请注意，这在我的IntellIJ上的Groovy 2.5.6上非常有效，但当我在当前运行在Groovy 2.4.12上的大型机z/OS上的基于Linux的OMV上执行它时，它就不起作用了。此外，我尝试了HTTPBuilder 0.5.0/0.5.2/0.7.1，但仍然有相同的响应。

我会加快日志记录，你看到真正发送的是什么了吗，或者只是尝试一下curl/httpie这台机器。错误可能意味着，您刚刚取回了某个网站（例如某个公司代理）。此外，

“$jsonObjtrim”

只是

jsonObjtrim

，因为它已经是一个字符串；RESTBuilder可以处理JSON序列化-您可以将

version

作为正文。@cfrick我不能在这台机器上使用CURL，因为它是z/OS上的Unix（IBM大型机）而且它的容器中没有卷曲。我尝试在put请求的主体中传递字符串而不是jsonobject，但得到了相同的响应。我在原始问题语句中添加了日志。groovy脚本在遵循EBCDIC编码的机器上运行，这会不会是一个问题，因为接收我的HTTP put的服务器是一个常规的L因努克斯机器？
