Proposed Solution

Thanks to this comment - nodejs/help#1846 (comment) - a working fix was to update the node version that's listed in the gh-pages.yml workflow file.

Link to my code change: kdipippo/daeclipse@5dac86f

Following the diff here should be able to future-proof if any others run into the same issue with attempting to deploy.

@Pepper-Wood First off, sorry for the +6 month delay. Many thanks for providing a fix!

I'm glad you find the extension useful. I recently had the time to upgrade the dependencies of this project to the latest version f4b2aa5

Please do not hesitate to let me know any other improvements you applied to daeclipse!
