One or more field types are not installed properly. Go to the list settings page to delete these fields.
Recently, I was using a Power Automate workflow to create folder structure inside SharePoint Document Set. Everything went well except... at workflow execution. I got an error message saying: One or more field types are not installed properly. Go to the list settings page to delete these fields . I had 27 fields to reviews. I decided to delete set of 3 fields and re-run my workflow and so on. The issue was due to a field that had encoded space at the end of his internal name like below. isProcessReviewed _x0020_ Luckily because my document library was empty so deleting fields was an acceptable solution otherwise we could have lose data. An other option could be extract list schema using PnP PowerShell and review list and fields definition.
