"TypeError: Failed to fetch" error when trying to upload a Pre or Post Script

Applies to: Patch My PC Cloud

SYMPTOMS

I am trying to upload a Pre (or Post) script, but I get the following error:

Error - TypeError: Failed to fetch

CAUSE

This error can happen if your pre/post script contains either of the following variables:

"${env:ProgramFiles(x86)}"

"${env:ProgramFiles}"

This issue is not caused by the Patch My PC (PMPC) Cloud portal but by Cloudflare, who are incorrectly identifying them as a false-positive and blocking the upload as they think the script is a Log4j exploit.

RESOLUTION

As Cloudflare is causing this issue, we cannot implement a fix. We are actively working with them to try to resolve this false positive.

In the meantime, to work around this issue, use the following replacements in your affected scripts:

Replace all instances of…	With...
"${env:ProgramFiles(x86)}"	"$($env:SystemDrive)\Program Files (x86)"
"${env:ProgramFiles}"	"$($env:SystemDrive)\Program Files"
