cloud storage 404 error while uploading files

[asantoni]

I am  doing an upload of files for further processing to a bucket on GCP. Most of the files uploaded fine. However for some 62 left of a total of several thousand i am getting a 404 message.

Something in this form

Resuming upload for wave/continuous/2016/LO/...
Resuming upload for wave/continuous/2016/LO/....

ERROR: gs://ospl.. not found: 404.                                                                                   
ERROR: gs://ospl... not found: 404.

All commands like

gcloud storage ls  gs://ospl....

 Work just fine, so I don't understand why I would be getting this url not found error.

Thanks for any help.

I think we are likely going to have to see the complete error messages returned.  It would also help to paint a picture of what commands you are running.   Where are the source files located?  I also notice the phrase "Resuming upload ..." .... could the upload have been interrupted and restarted but the original source files changed/deleted between the original request and now?
