Environment Name in the testexecutions api

Hi Team, we use testexceutions (under create Test execution) api in a powershell script by passing the values to the parameters testcycleKey, TestCaseKey, StatusName, executedbyID to update the test case status on the Zephyr.

Problem is with the environment name, When environment name is assigned to the test cases under test cycle prior execution then when the script is triggered to update the test execution status then the test case will be copied (without environment name) and execution status will be updated for the copied test case. Please suggest on how to not get a copy of the test case and execute the test case though the environment is assigned.
