Pattern Import Failure y.values ().find is not a function.

I exported my WordPress block pattern, tried to import the pattern on other WordPress site and got this error:

y.values ().find is not a function. (In 'y.values).find ((e=>e.name===n)); 'y.values().find' is undefined

I validated the JSON at https://jsonlint.com and it is valid. File to be check is here https://gist.github.com/jasperf/4747e963fc84871ea6f3482ddf37381e I added the custom line block it uses as must-use plugin and still the same error on import. This is a major problem for me.

Worked on this menu pattern for a long time and I need to be able to export it. Using it locally and synch one used on a page with the actual pattern and that works well. But I need to be able to use it elsewhere.
