I think btown's sibling comment has it right. It's not even a prototype if it isn't demonstrating some aspect of its core capabilities.

Given this line from the article:

    Despite the early September memo’s scathing critique, Leonel Garciga, Army chief information officer and Chiulli’s supervisor, said in a statement to Reuters that the report was part of a process that helped in “triaging cybersecurity vulnerabilities” and mitigating them.

and

    Other deficiencies highlighted in the memo include the hosting of third-party applications that have not undergone Army security assessments. One application revealed 25 high-severity code vulnerabilities. Three additional applications under review each contain over 200 vulnerabilities requiring assessment, according to the document.

it seems like there was a SIGNIFICANT mismatch in expectations between the team delivering the prototype and the people receiving it. Everyone's time was wasted as a result.
