Jupyter fails to open notebook using MinIO #96

Closed edergillian closed 3 years ago

edergillian commented 4 years ago

I got this error when trying to create a notebook on MinIO:

Traceback (most recent call last): 
File "/opt/conda/lib/python3.7/site-packages/tornado/web.py", 
  line 1703, in _execute result = await result

  line 416, in _convert_header_value raise TypeError("Unsupported header value %r" % value) TypeError: Unsupported header value None

The file is actually saved on MinIO, but it does not open on Jupyter Notebook web GUI

This is my configuration:

from s3contents import S3ContentsManager

c = get_config()

# Tell Jupyter to use S3ContentsManager for all storage.
c.NotebookApp.contents_manager_class = S3ContentsManager
c.S3ContentsManager.access_key_id = "**"
c.S3ContentsManager.secret_access_key = "**"
c.S3ContentsManager.endpoint_url = "http://minio.minio:9000/"
c.S3ContentsManager.bucket = "bucket"
c.S3ContentsManager.prefix = "prefix"
c.S3ContentsManager.signature_version = "s3v4"

This is probably not an issue in newer versions pls open a new issue if this is still the case.
