Failed to parse source map

[peekpi]

I use this package in my frontend project, and when I run yarn start, there are many warnings like:

Failed to parse source map from 'project/node_modules/json-rpc-protocol/src/json-rpc.type.ts' file: Error: ENOENT: no such file or directory, open 'project/node_modules/json-rpc-protocol/src/json-rpc.type.ts'

I guess should add "src/" to files array in package.json?

json-rpc-protocol/package.json

Lines 27 to 29 in 7a6387d

	"files": [
	"dist/"
	],
