API Vertex AI RAG Engine: Upload file in corpus failed

[eric734574]

Hi Team,

I'm playing with AI Platform and the RAG engine. Amazing feature, works well, except for the specific Upload File in corpus API, throw API or even a Java implementation

I've created my RAG Corpus.  I've imported (import , not upload) files throw GCS resources  and check my corpus with RAG file list.  All sounds good. 😊

BUT.... 

 Upload RAG file failed. I get a HTTP 200 with en empty response, and the file is not imported. (File list in the corpus stay empty 😕 )

My POST

curl -X POST \
-H "X-Goog-Upload-Protocol: multipart" \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-F metadata="{'rag_file': {'display_name':' test-api', 'description':'test-des-api'}}" \
-F file=@./test.txt \
"https://europe-west3-aiplatform.googleapis.com/v1/projects/MYPROJECT/locations/europe-west3/ragCorpora/CORPUSID/ragFiles:upload"

I get the HTTP 200 with body

{
  "ragFile": {}
}

I get the same result throw Java implementation

Other issue, the URL given in the documentation  is

https://LOCATION-aiplatform.googleapis.com/upload/v1/projects/PROJECT_ID/locations/LOCATION/ragCorpora/RAG_CORPUS_ID/ragFiles:upload

and seems wrong . Get a 404 with the link.

Right link seems to be 

https://LOCATION-aiplatform.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/ragCorpora/RAG_...

Your help will be appreciated to understand what's wrong in this file upload into my RAG corpus.

Thanks !!!!
