邮件触发出现ValueError: the environment variable is longer than 32

Task Failed, Traceback (most recent call last): File "D:\ShadowBot\shadowbot-5.14.38\python\lib\runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "D:\ShadowBot\shadowbot-5.14.38\python\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "D:\ShadowBot\shadowbot-5.14.38\python\lib\site-packages\xbot_interpreter.py", line 97, in main() File "D:\ShadowBot\shadowbot-5.14.38\python\lib\site-packages\xbot_interpreter.py", line 49, in main os.environ[env_key] = env_value File "D:\ShadowBot\shadowbot-5.14.38\python\lib\os.py", line 684, in setitem self.putenv(key, value) ValueError: the environment variable is longer than 32767 characters

请问一下，这是什么情况，其他的程序正常邮件触发；这个程序前几次都是正常触发，后面也能触发，就是触发后运行第一秒就报这个错误；环境变量也没有手动修改过；谢谢各位，麻烦高手能解答一下
