We have received some reports about the error thrown Target.setDiscoverTargets by Puppeteer. We can try to improve making connection to the spawned Chrome.

Possible workarounds

• If failed making connection with Chrome in pipe: true option, we can try to launch Chrome again with pipe: false for making connection through WebSocket instead of pipe.

Any timeline frame for this release? I will be teaching a class in February and I really like to utilize this feature.

It would be included in the next patch release that will be shipped in a month a week. A monthly patch for Marp CLI is just delayed now because I'm currently working on Marpit v3 and Marp Core v3.
