Using Java client DgraphClient remove Dgraph fields to add fields when title description of mistakes occasionally, I found there is an asynchronous object DgraphAsyncClient DgraphClient, DgraphClient database operation is asynchronous operations, if so, I doubt these errors may be didn’t delete fields, is to add fields to, but I am not sure whether the problem

The detailed error information is as follows
io.grpc.StatusRuntimeException: UNKNOWN: error opening temp badger for reindexing: open C:\Users\ADMINI~1\AppData\Local\Temp\2\dgraph_index\630960637\MANIFEST: The system cannot find the file specified.

Hi @wangliujing, can you tell us a few things to understand your problem better.

  1. Which version of Dgraph are you using?
  2. Steps to reproduce this error.
  3. Are you facing it every time or just sometimes.
  1. Dgraph version is V2.0.0-beta
  2. Delete the Dgraph field and then rebuild the field. These two steps are executed in the same method
  3. This mistake doesn’t happen every time. It’s probabilistic
