Error message

Instagram reel upload requires Browser Bridge file upload support

What it means

uploadVideo requires the page object to expose setFileInput for programmatically attaching files to a file input. If page.setFileInput is undefined it throws CommandExecutionError saying reel upload requires Browser Bridge file upload support. Without this capability the library cannot put the local file into Instagram's upload input.

Solutions

1. Run the command with Browser Bridge (or another mode supporting setFileInput) as the browser backend.
2. Upgrade Browser Bridge/driver to a version exposing setFileInput.
3. Implement setFileInput on a custom page adapter to delegate to the underlying driver's file-upload API.
4. Verify the active browser mode before posting (feature-check page.setFileInput).

Example fix

// before
const page = await connectBasicDriver(); // no setFileInput
await runReel(page);
// after
const page = await connectBrowserBridge(); // supports setFileInput
await runReel(page);

if (typeof page.setFileInput !== 'function') throw new Error('Current browser mode lacks setFileInput; use Browser Bridge');

function supportsFileUpload(page) { return typeof page?.setFileInput === 'function'; }

try { await reel(args); } catch (e) { if (e.message.includes('setFileInput')) { console.error('Switch to Browser Bridge: e.g. set browser mode to browser-bridge and reconnect.'); return; } throw e; }

When it happens

Trigger: Running the reel flow with a browser mode that lacks setFileInput — plain automation pages, older Browser Bridge versions, or drivers that only expose evaluate/wait but not file upload.

Common situations: Using a legacy browser driver, Browser Bridge not upgraded to the version adding setFileInput, or a custom page adapter that doesn't implement the method.
