failure is related bcoe/c8#592

@mcollina should i skip test coverage on node.js 26? or wait for the issue to be fixed.

[mcollina]

we can wait a few days

[shivarm]

We have this option to fix ci for now or we should still wait...?

"overrides":{
  "yargs": "^18.0.0"
},

[mcollina]

I dont think the yargs change is needed anymore, can you verify?

[shivarm]

@mcollina They have released c8 new version which contain latest yargs https://github.com/bcoe/c8/releases/tag/v12.0.0 but on npm registry I can't see and here you can find discussion bcoe/c8#592 (comment)

[shivarm]

Actually my bad, I verify on npm that this is not a stable release but upgrade c8 dep let's see
