Browser provider is not available yet: ${requestedProvider}

Error message

Browser provider is not available yet: ${requestedProvider}

What it means

openBrowserUrlForAutomation only accepts provider values 'auto' or 'builtin' (after trim/lowercase). Any other non-empty provider string throws this error because alternate browser providers are not implemented in this build.

Solutions

1. Omit the provider argument (defaults to 'auto')
2. Pass provider: 'builtin' explicitly
3. Fix the provider string casing/spelling so it normalizes to 'auto' or 'builtin'
4. Remove third-party provider selection — it is not supported yet in this build

Example fix

// before
await openBrowserUrlForAutomation(url, { provider: 'chrome' });
// after
await openBrowserUrlForAutomation(url, { provider: 'builtin' });

const ALLOWED = new Set(['auto', 'builtin']);
if (provider && !ALLOWED.has(String(provider).trim().toLowerCase())) {
  throw new Error(`provider must be 'auto' or 'builtin', got ${provider}`);
}

function isBrowserProvider(v) { return typeof v === 'string' && ['auto','builtin'].includes(v.trim().toLowerCase()); }

try {
  await openBrowserUrlForAutomation(url, { provider });
} catch (e) {
  if (e.message.startsWith('Browser provider is not available yet')) {
    // fall back to default provider (omit the option)
    await openBrowserUrlForAutomation(url);
  } else throw e;
}

When it happens

Trigger: Calling the browser automation API with provider set to something like 'chrome', 'external', 'system', or a typo such as 'BuiltIn' spelled differently after normalization (e.g. 'built-in').

Common situations: Passing a provider name copied from docs for a future/planned provider; typos like 'built_in'; callers hardcoding a provider that an older/newer build expects but this one rejects.
