For example, shouldn't the connector replace %TEMP% with C:\Users\rhipp\AppData\Local\Temp\?
Something's off here, especially since it saves the files in a folder where the name still contains the % literal.
@rhipp87 can you share the workflow?
isn't %TEMP% a global variable (in your environment variables on your system)? %Workflow.TempFilePath% might be the one you're looking for?
https://knowledge.alteryx.com/index/s/article/All-About-Constants-1583459845970 that's the under your workflow constants in Alteryx.
It may depend, tool to tool, where you can and can't use %TEMP%.
If that Sharepoint Tool is using Python under the hood for the API piece I suppose it may use the OS module to grab the environment variables via os.environ.
Not sure if that solves your problem but it could explain the conflict your facing.
All the best,

I should mention that the default path in the SharePoint input tool is %TEMP%/SharePoint.
I'm hoping someone else can use SharePointInput_2_6_1 and confirm the same behavior.
