ComputerProfileUploader fails with integer key values

[mhrono]

I'm attempting to create a configuration profile during a recipe run to place update metadata on devices for later use. One piece of data included in the profile is the size of the update package. I've found that when this key is added to my payload template, the profile processor step in my recipe fails. This failure occurs regardless of if the payload specifies it as <integer> or <string>. If I remove the variable containing the integer or substitute it with something non-numeric, the profile is created and uploaded successfully.

This should be reproducible with the following recipes and templates from my repo:
Recipe: 1Password8.jamf
Profile template: ConfigProfileTemplate-autopatch.xml
Payload template: payloadTemplate.plist

Additionally, my forked version of the PkgInfoReader processor is required in order to get the %installer_item_size% value. I also have a pull request open to merge the update into the main processor.

Here's a sanitized -vvvv output of the ComputerProfileUploader step in a failed run:
