any idea?
thanks.
maybe it is ES docker image related M1 issue only?

Have you checked the FAQ document?

Have you checked the FAQ document?

where is it ? in README.MD. thanks.

Make sure the code you pull and docker image you pull are on the same version.
Do not use main branch code to run 0.7.0 version of docker image.

did you mean change the version from of Elastic products
STACK_VERSION=8.11.3 to 0.7.0 in .env file?

Make sure the code you pull and docker image you pull are on the same version.

even though after running ```docker-compose up -d , and verified rag flow-es01 is healthy, because of /ragflow/api/ragflow_server.py", line 26, in triggled File "/ragflow/rag/utils/es_conn.py", line 24, in _init, right?

No. It refers to the version of RAGFlow docker image.
I suggest you to use dev version of docker image and pull the latest code.

Again， after git reset --hard HEAD, docker-compose -f docker-compose-base.yml, move out ragflow_erver.py out of the api file folder, then direct run python ragflow_erver.py, errors thrown as following :

Connection error caused by: ProtocolError(('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')))

                    ^^^^^^^^^^^^^^

any idea? or any documents with this debug way. thanks.

[yangboz]

maybe is "" http://es01:9200)" in codebase debug level , the domain of http://es01 is not working , should be replaced with localhost or 0.0.0.0?
