Built a custom Browserless image with the v2 SDK (npx @browserless.io/browserless create, then npm run docker). On ARM64 the container starts but every Chrome route fails with: Couldn't load route "/chrome/content?(/)" due to missing browser binary for "ChromeCDP". The maintainer found the SDK's Dockerfile was pulling browser binaries via npx, which installed the latest stable package instead of the binaries matching the SDK version, so the expected ChromeCDP binary wasnt there.

Fixed in the Browserless v2 SDK. Upgrade to @browserless.io/browserless 2.30.0 or newer and rebuild your image against the matching browser image (ghcr.io/browserless/chromium) on linux/arm64. The original reporter confirmed the missing-binary error is gone on 2.30.0, and the maintainer closed the issue as solved from their testing.
