Portal API content.add and .publish overwrite option not working

[chris_del101]

I'm trying to add a feature layer to portal and I get the error, even though I include overwrite=True:

Exception: {'message': "Service name 'myService' already exists for '123abc'"}
Arguments: (Exception('Unable to Add messages Job Event\nUnable to Add messages Job Event\n(Error Code: 500)'),)

I am including overwrite in the properties and in the function itself, just in case at least one might work, yet it does nothing. It's specified here .

The content.add problem can be overcome by either deleting the item from portal, or adding a script to do it, but the .publish one is fatal. I DO NOT have any item with that name and this error is still occurring. How do I make the overwrite param work?

 item_properties = {
        'title': itemTitle,
        'type': 'File Geodatabase',
        'description': item.description,
        'accessInformation': item.accessInformation,
        'licenseInfo': item.licenseInfo, 
        'overwrite': True
    }
fgd = trg.content.add(item_properties=item_properties, owner=username,
                                 data=download_result,  overwrite=True)
targetService = fgd.publish(overwrite=True)

I am not looking for a better way to do this overall, but to solve this issue.

Hi @chris_del101,

What version of Enterprise and what version of the ArcGIS API for Python are you using?

[chris_del101]

Hi @JakeSkinner, this taken from your migration tools for Pro. I am having trouble authenticating with those but the code looks useful.

Enterprise: 11.3.0

arcgis PY: 2.4.0

@chris_del101 try the following:

item_properties = {
        'title': itemTitle,
        'type': 'File Geodatabase',
        'description': item.description,
        'accessInformation': item.accessInformation,
        'licenseInfo': item.licenseInfo,
        'overwrite': True
    }
root_folder = trg.content.folders.get()
fgd = root_folder.add(item_properties=fgd_properties, file=download_result).result()
targetService = fgd.publish(overwrite=True)

Note:  The property `overwrite` is deprecated and support will be removed two releases after 2.4.0 for the item_properties.

I tried a layer and this seemed to solve that problem, but not for long. I hit some other errors now, and they are just cryptic af.

I was able to copy a layer once, but when I tried a different layer I got this with no additional information.

result_item = item.export(itemTitle, 'File Geodatabase', wait=True)

I went back to the first item and tried it again I get this. It makes a new folder first, so it's not an issue of existing items existing
