How to fix npm ERR! code EFUNDINGINVALID npm ERR! Invalid funding configuration in npm

npmBEGINNERLOW

The funding field in package.json is invalid. Use a valid URL/object/array per npm funding spec.

What this error means

npm validates the funding field. Invalid types or malformed entries cause EFUNDINGINVALID during publish or install warnings.

1Use the correct funding format

Examples:

String URL:

json

"funding": "https://github.com/sponsors/you"

Object:

json

"funding": { "type": "individual", "url": "https://github.com/sponsors/you" }

Array of objects is also allowed.

2Validate URLs

Ensure funding URLs are valid HTTP(S) links.

3Republish or reinstall

After fixing funding, rerun npm publish or npm install.

Funding metadata is optional; keep it accurate to avoid warnings. Follow npm’s funding schema.
