OSS-Fuzz Build Fuzzers in Workspace Issue

I am trying to set up a project where I use OSS-fuzz to extend cJSON's code coverage. As I am super new to this field, I am following a video for reference, which watching it may help:
https://www.youtube.com/watch?v=7bvRbESPdlM

Basically my error is approximately at 5:45 in the video. I go to build the fuzzers in the workspace after setting up the OSS-Fuzz, and I am given this output followed by an error:

I am uncertain as to how this error is coming up as to what it means. For context, my VSCode is version 1.86.2, and I am running this on Linux. I am uncertain what could be wrong with the Dockerfile as the error says because the code (including dockerfile) I got was the exact same one from the video. Any suggestions on where this error could be coming from/how to fix it?
