npm publish fails with "The "path" argument must be of type string. Received undefined"

Question

I have a project that i publish on a private npm repository. Under node v14.16.0 (npm v6.14.11), the command npm publish run well and my package is published on my private repository.

I upgraded npm to 7 to support peer dependencies installation. Now under node v15.12.0 (npm v7.6.3), the command npm publish fails with

The "path" argument must be of type string. Received undefined

Any idea?

Update

npm 7.6.3 with node 14 as the same effect :

The "path" argument must be of type string

Update 2

console output with flag --verbose

I found the issue here

The workaround is to add a cache property to the publishConfig section of package.json

"publishConfig": {
    "cache": "cache/.npm",
    "registry": "https://mydomain/myrepo"
}

Update

The issue has been fixed in npm 7.7.0
