No Chrome download found for platform 'linux64'

Error message

No Chrome download found for platform 'linux64'

What it means

Raised by the chrome() function in pinned_browsers.py when the selected Chrome version's downloads JSON contains no 'chrome' entry with platform 'linux64'. The function searches chrome_downloads (selected_version['downloads']['chrome']) for d['platform'] == 'linux64'.

Solutions

1. Retry after a delay — linux64 Chrome may appear shortly.
2. Verify the JSON payload manually to confirm linux64 Chrome exists for the milestone.
3. Update the script if the platform key or download structure changed upstream.

Example fix

null

chrome_downloads = selected_version['downloads']['chrome']
platforms = [d['platform'] for d in chrome_downloads]
if 'linux64' not in platforms:
    print(f'linux64 not in available platforms: {platforms}')

null

null

When it happens

Trigger: Running pinned_browsers.py when Chrome-for-Testing has not published a linux64 Chrome binary for the target milestone; JSON schema change; the milestone filter selected a version without linux64 Chrome downloads.

Common situations: Release transition window; upstream JSON format change; CI timing during Google's release cycle; network issue returning a partial/truncated JSON response.
