Error while updating Feature Layer data: Invalid Field Type

[MichelleK_NSLA]

Hi all. 

Very new to ArcGIS Online, and struggling with updating the data for a Feature Layer in my map.

When I run through the Update Data process, I am able to upload my .csv, define my location settings (fields "Latitude" and "Longitude"), indicate my Unique Identifier (field "Id"), and match all fields. All field types in my .csv appear to match with the existing field types. 

However, once I click Update and Complete I get the error, "Invalid Field Type".

Any thoughts on how I might troubleshoot the issue? Any direction would be sincerely appreciated.

Hey Michelle,

I was able to find a related previous post and the following documentation

It appears to be an issue within the data itself. I believe there to be quite a few good solutions within that previous post. Please refer to the documentation to read more about generic errors from uploading and published CSV files as hosted feature layers.
