[FlowiseAI] Installation failed

[frontend-report]

Script: FlowiseAI

Reported by: @yorkshirelandscape

Guidelines

• Read and understood guidelines: yes
• Verbose mode used: yes

Issue occurs during: Initial Creation / Installation

Environment

• Linux distribution: Debian
• Proxmox version: 9.1
• Default settings: Yes
• Advanced settings: No
• Exact command: bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/flowiseai.sh)"

Description

There's a point in the installation where it errors out saying that the user didn't respond to a prompt without ever offering the prompt. That seems like it's the result of a package not being found. I'll also note that it generates mountains of node package deprecation warnings during installation before it gets to this step. I figure that might be expected with this sort of thing, though.

Steps to reproduce

1. Run the install script.

Docs offer conflicting informations, some place it says use npm, some it says pnpm. It definitely should use pnpm but flowise package is not recognized as it should...

@MickLesk can you take a look?

No matter if you installit like pnpm install -g flowise or pnpm install -g flowise@3.1.2, every time you run it with npx flowise start it asks to install flowise@3.1.2 again... so weird
