Fixing 404 Errors for Wakanda v2.4.0 Data Browser Requests

Hey there! Let's work through those 404 errors you're seeing with the old Data Browser in Wakanda v2.4.0. I've run into similar migration hiccups when moving from 1.x to newer versions, so here are actionable steps to fix this:

1. Verify Your Webfolder Path Mapping

First, double-check how you've configured the Webfolder for your WALIB directory. The 404s are happening because the Data Browser is still requesting resources at /db/walib/..., but your Webfolder is mapped to /walib (since you can access the index page at localhost:8081/walib/dataBrowser/index.html).

Open Wakanda Studio's backend configuration panel.
Locate your WALIB Webfolder entry, and confirm its Path Prefix is set to /walib (not nested under /db). If it was set differently, update it and save the configuration.

2. Update Hardcoded Paths in Data Browser Files

Wakanda 2.x overhauled its backend routing structure, so the old Data Browser code likely has hardcoded references to /db/walib. You'll need to update these:

Navigate to your copied walib/dataBrowser directory.
Open index.html and any related JS files (like app.js, data-service.js, or similar) in a text editor.
Search for all instances of /db/walib and replace them with /walib. For example, change a request like fetch('/db/walib/api/getSchema') to fetch('/walib/api/getSchema').

3. Check File Integrity and Webfolder Permissions

Sometimes missing files or incorrect permissions can trigger 404s:

Confirm you copied the entire WALIB directory (including all subfolders and files) to your Webfolder location—don't skip any API or asset files.
In Wakanda's Webfolder settings, verify the Access Control is configured to allow access to the resources. If you're testing locally, setting it to allow anonymous access temporarily can rule out permission issues.
