Hello
This thread has been so helpful, and i would like to thank all of you in advance for all the information. I am facing similar situation as the original problem. This thread is three year old but i was wondering if there is any solution.
I have ARC 10.3 in my desktop . I am trying to publish mxd file automatically using python script , i used similar code posted in this thread. But it is showing error , unless i signed in manually through the ARCmap it wont publish the map. The error is as follows
ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000732: Server: Dataset My Hosted Services does not exist or is not supported
WARNING 001404: You are not signed in to ArcGIS Online.
Failed to execute (UploadServiceDefinition).
Can you please post is as a file or text with line breaks included?
