silgen opened a new issue, #5803: URL: https://github.com/apache/jmeter/issues/5803
### Expected behavior _No response_ ### Actual behavior _No response_ ### Steps to reproduce the problem Previously: When using jmeter for interface testing, the request body was parameterized, and the execution result reported an error. But without parameterization, the execution result is successful, and after parameterization, the parameters read in the request are correct (the parameters at the time of execution failure and success are consistent). Problem troubleshooting: After parameterization, the two backslashes in the request have become one backslash. Problem reason: During parameterization, ${} escaped the backslash. Solution: Replace the single backslash with a double backslash.
