[问题求助]网络接口调用

     # 2. 组装 JSON 报文
     LET requestData = SFMT(
         '{"messageKey":"%1","value":"%2","customEnumerationCode":"Project"}',
         p_project_code,
         p_project_name
     )
 
     TRY
         LET req = com.HTTPRequest.Create(url)
         CALL req.setTimeOut(120000)
         CALL req.setMethod("POST")
         CALL req.setHeader("Content-Type", "application/json")
 
       CALL req.setHeader(
           "Authorization",
           "Bearer "|| p_token.trim()
       )
        CALL req.doTextRequest(requestData)
        LET resp = req.getResponse()
          IF resp.getStatusCode() = 200 THEN
                LET responseText = resp.getTextResponse()
                CALL util.JSON.parse(responseText, res_rec)
               RETURN TRUE
            ELSE
                ERROR SFMT("HTTP请求失败，状态码: %1", resp.getStatusCode())
                RETURN FALSE
            END IF
            RETURN TRUE
 
     CATCH
         ERROR SFMT("网络调用异常或JSON解析失败: %1", STATUS)
       DISPLAY "g_enterprise = ", g_enterprise
        DISPLAY "url = ", url
     END TRY
调用这个LET responseText = resp.getTextResponse()语句的时候系统直接崩溃走到catch，如何解决？

崩溃信息如下Breakpoint 1, cglp341_send_context() at cgl_cglp341.4gl:857
