Fix configs not loading when configs folder contains subdirectories (#1392)

[SukuWc]

Problem

Fixes #1392. When the grid-userdata/configs folder contains a subdirectory — most commonly a .git folder when the user puts the configs under source control — all or some configs disappear from the editor due to a runtime error during directory read. Deleting the subdirectory makes them reappear after restarting the App.

Root cause

loadConfigsFromDirectory (src/electron/src/profiles.ts) did a flat readdir and called fs.promises.readFile() on every entry with no type check and no error handling:

const files = await fs.promises.readdir(`${path}/${rootDirectory}`);
for (const file of files) {
  await fs.promises.readFile(filepath, "utf-8").then(...); // EISDIR on a directory
}

The moment it hit a directory entry, readFile rejected with EISDIR, the unguarded await threw, and the entire function rejected — so the renderer got zero (or some but not all) configs instead of just skipping the directory.

Reproduced against a real configs folder: the original loop threw EISDIR; the fixed loop loads all configs.

Why no error showed in the console

The initial load runs in the main process via the watcher's fire-and-forget sendLocalConfigs() (no await, no .catch). The rejection became an unhandled main-process rejection, invisible to the renderer DevTools console, and webContents.send("sendConfigsToRenderer", ...) simply never ran — a silent empty state.

Changes

• profiles.ts: read with withFileTypes and only process .json files, skipping subdirectories and other entries. Each read is wrapped in try/catch so one bad/corrupt file can't abort the rest.
• main.ts: wrap the watcher's sendLocalConfigs() body in try/catch so a load failure is logged via log.error instead of becoming a silent unhandled rejection.
• main.ts: drop the custom %c coloring on [ELECTRON] forwarded logs (plain prefix now).

Testing

• Type-checks clean (tsc --noEmit).
• Verified the load logic against a real configs folder containing a subdirectory: original throws EISDIR → 0 configs; fixed → all configs load.
