Proposed fix: [Playwright MCP] Config conflicts: 'Browser userDataDir is not supported in isolated mode.' / 'Cannot use --mobile together with --device' / 'Device emulation is not supported with cdpEn
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Drop one of the conflicting options (check PLAYWRIGHT_MCP_* env vars too).
Option: Drop one of the conflicting options (check PLAYWRIGHT_MCP_* env vars too). [evidence: official_recommended_action]
Applies when: Combining --isolated with --user-data-dir, --mobile with --device, or --device with --cdp-endpoint
Steps:
1. Remove --user-data-dir when using --isolated (use --storage-state for initial state)
2. Pick --mobile or --device
3. Don't use device emulation when attaching via --cdp-endpoint
Expected: The error no longer appears.
