[BUG] An error occurred using thread isolation mode in Hystrix Plugin

[tswc1989]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Use Shenyu V2.6.1 to enable Hystrix. When the isolation mode is semaphore, it is normal. When the isolation mode is thread, similar to this case: #2893 error is as follows:
