How are you running AnythingLLM?

AnythingLLM desktop app

What happened?

Environment:

  • AnythingLLM version: 1.12.0 (desktop)
  • OS: Windows 11
  • Hardware: i9-13900K, 64GB RAM, RTX 4090 24GB VRAM
  • LLM backend: LM Studio (local)
  • Model: Qwen3.5-35B-A3B Q4_K_M

Description:

The exceljs module bundled with ALLM is missing its lib/doc directory, causing all Excel file creation to fail with a module error. The agent falls back to CSV informing the user. Attempting to fix this via npm install exceljs destroys the ALLM node_modules tree, requiring a full reinstall.

Reproduction steps:

  1. Enable Document Creation skill with Excel enabled
  2. Ask the agent to create any Excel file
  3. Observe backend error: Cannot find module './doc/workbook'
  4. Agent falls back to CSV

Verify the missing directory:

ls "C:\Users\{username}\AppData\Local\Programs\AnythingLLM\resources\backend\node_modules\exceljs\lib"

doc directory is absent from the shipped bundle.

Expected behavior:
Excel file is created successfully, or failure is clearly reported to the user.

Actual behavior:
Excel creation fails due to missing lib/doc in the bundled exceljs 4.4.0. Agent falls back to CSV without disclosing the error.

Warning — do not attempt npm install exceljs:
Running npm install exceljs in the ALLM backend directory removes approximately 1,080 packages from node_modules, breaking ALLM entirely. Recovery requires a full application reinstall.

Workaround:
Download the complete exceljs 4.4.0 tarball directly from npm and manually copy the missing lib/doc folder:

Invoke-WebRequest -Uri "https://registry.npmjs.org/exceljs/-/exceljs-4.4.0.tgz" -OutFile "$env:USERPROFILE\Downloads\exceljs.tgz"
cd "$env:USERPROFILE\Downloads"
tar -xzf exceljs.tgz
Copy-Item -Recurse "package\lib\doc" "C:\Users\{username}\AppData\Local\Programs\AnythingLLM\resources\backend\node_modules\exceljs\lib\doc"

Restart ALLM after copying. Excel download links then work correctly.

Are there known steps to reproduce?

Reproduction steps:

Ah, we have some custom build scripts to prune READMEs and docs and other files that are relevant but bloat the node modules. They got pruned by accident here. It is patched now and will be resolved in next patch release
