sshniro opened a new issue #1181: bug: coroutine.wrap:20: API disabled in the 
context of log_by_lua error in Batch Processor
URL: https://github.com/apache/incubator-apisix/issues/1181
 
 
   Hi,
   
   When using the [batch 
processor](https://github.com/apache/incubator-apisix/blob/e1ac426443293c6140ddb257e482537edd43c36a/lua/apisix/plugins/batch-processor.lua#L110)
 inside the _M.log phase the system throws the following error.
   
   This happens when I use core.schema.check(schema, config) inside the batch 
processor. 
   If I use a simple validation (if/else) then the workflow is working without 
an error.
   
   ```lua
   2020/03/02 15:36:40 [error] 5155#5155: *237 failed to run log_by_lua*: 
coroutine.wrap:20: API disabled in the context of log_by_lua*

   ```
   
   Is this a limitation? Some guidance would be helpful.
