@Kylejeong2 is attempting to deploy a commit to the Vercel Labs Team on Vercel.

A member of the Team first needs to authorize it.

Additional Suggestions:

1. Lines 246 and 256 use hardcoded ANSI color codes instead of color module's error_indicator() function, bypassing NO_COLOR environment variable

2. Line 357 uses hardcoded ANSI escape codes instead of the color module's error_indicator() function, bypassing NO_COLOR environment variable support

	const connected = await this.connectToBrowserbase();
	if (!connected) {
	throw new Error(
	'BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID are required when using browserbase as a provider'
	);
	}
	return;
	try {
	const connected = await this.connectToBrowserbase();
	if (!connected) {
	throw new Error(
	'BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID are required when using browserbase as a provider'
	);
	}
	return;
	} catch (error) {
	// Ensure a descriptive error message is thrown
	if (error instanceof Error && error.message.includes('BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID are required')) {
	throw error;
	}
	throw new Error(
	`Failed to connect to Browserbase: ${error instanceof Error ? error.message : String(error)}`
	);
	}

When provider='browserbase' is explicitly set, missing env vars produce one error message while API/network failures produce different raw errors, causing inconsistent error handling
