@tiagochst,

Thank you for reporting the issue and include detailed information! We appreciate it. Our synapser wraps our Python client. However, synapser manages its own Python environment and this Python environment is separated from user's Python environment. In the Python environment that is managed by synapser, we do not include pysftp package.

You probably running into this issue because you were downloading/uploading files that are hosted from an SFTP server and linked to Synapse. synapser client is not supporting this usage.

Although, perhaps we should throw a more reasonable error in this case. I would advice to use out web client or our Python client to download/upload these files.

The folder that you are uploading the file to has storage setting set to sftp:

Thanks! I used the Python client and I was able to upload the data.
