arcgis.gis.ContentManager clone_items remap_data error IndexError: list index out of range

[chrisdel101]

Describe the bug
When calling remap_data I get an error.

Both the src and target IDs that are failing exist in the target portal.
Example w failed IDs:
webmap[0].remap_data({'55e1aa9e034a41c5a7f05c6077ce14e5':'e6d17cef0f21497da6adccac3736bbec'})

To Reproduce
Since it only does it for some ids it's not straightforward to reproduce.
It works for some of the ids, but not for others. I have 5 entries in a dict. It remaps two then fails on the third, even though their is no visible difference between them.

error:
