   @spacewander It seems that there is still a problem after I use your repaired version.

   The problem is that the clear_header_as_body_modified function is nil.
   
   I suggest you need to upgrade the apache apisix code, not just the `echo.lua` file!

   It is a known issue.
   > NOTE: echo plugin is written as an example. There are some unhandled cases and you should not use it in the production!

   The plugin doesn't set Content-Length correctly.

   @thekingofworld 
   Because the fix depends on function introduced after 2.0.
   If the echo plugin is important to you, you should try the master branch.
