I have a flow that creates a file in a Sharepoint document library on the press of a button. I am trying to test it, but it only can create files that are one folder deep in the document library. Whenever I try to create a file that would be two folders or more deep in the Sharepoint library, it sends back a BadGateway Error. This is what I am attempting to do:

And this is the error message that it spits back to me:
message": "BadGateway",
"innerError": {
"status": 502,
"message": "The file or folder name \"Administration/IT/Dropbox Test /elmo\" contains invalid characters. Please use a different name. Common invalid characters include the following: # % * : < > ? / |\r\nclientRequestId: 878fb54f-e4f4-47e6-ad9e-bca6afc1db7b\r\nserviceRequestId: 3401979e-7020-6000-d5cf-41c7a2e381d5;3401979e-102e-6000-d5cf-4a5aa3536326",
"source": "https://thecartercenter.sharepoint.com/Administration/IT/_api/web/folders/add(@p)?@p='%2fAdministration%2fIT%2fDropbox+Test+%2felmo'",
"errors": [
"-2130575245",
"Microsoft.SharePoint.SPException"
For some reason, it seems to be replacing the second folder "/test" with a "\", which then produces an invalid character error. I have replicated this issue with numerous folder names, I have never run into this issue with creating files before, so any help on how to solve this would be greatly appreciated!
