How to append GUID data from Pro to Arc Online?

I need to append data that's stored in a file geodatabase to a web feature layer. I have created a GUID on the web feature layer, but when I try to append the file geodatabase's foreign key to the web layer I get the following:

 

Failed on input OID 3922, could not write value '{028C6C51-9C71-4D14-8E4C-0FA1B5B49A6F}' to output field preserve_guid

 

Additionally, when I try to use the admin "services" to "update" the field, I notice:

"name" : "preserve_guid",
"type" : "esriFieldTypeGUID",
"alias" : "Preserve GUID",
"sqlType" : "sqlTypeOther",
"length" : 0,
"nullable" : true,
"editable" : true,
"visible" : true,
"domain" : null,
"defaultValue" : null

I don't know if length matters for GUID, but it is 38 for the other GUID types in my layer. Okay, I'll just update the length to 38. Here's the same fields after "successfully" "updating":

"name" : "preserve_guid",
"type" : "esriFieldTypeGUID",
"alias" : "Preserve GUID",
"sqlType" : "sqlTypeOther",
"length" : 0,
"nullable" : true,
"editable" : true,
"visible" : true,
"domain" : null,
"defaultValue" : null

What is going on?
