Jest toEqual is failing and I don't know why - jestjs

Question

I'm running the tests for a package I'd like to help contribute to. However, when running the tests, which I'd assume should work, I'm getting a myriad of failing tests with this kind of output.
● PagingType › should create the correct filter graphql schema
expect(received).toEqual(expected) // deep equality

+ Received + 20

It seems like "toEqual" just isn't working correctly, because there seems to be nothing actually wrong between the two text outputs.
This is another set of example outputs of a console.log of the strings being compared. The failures are also happening with objects too.
type Query {
updateTest(input: UpdateOne!): Int!
}
input UpdateOne {
"""The id of the record to update"""
id: ID!
"""The update to apply."""
update: FakeUpdateOneType!
}
input FakeUpdateOneType {
name: String!
}
type Query {
updateTest(input: UpdateOne!): Int!
}
input UpdateOne {
"""The id of the record to update"""
id: ID!
"""The update to apply."""
update: FakeUpdateOneType!
}
input FakeUpdateOneType {
name: String!
}
Does anyone have an idea what might be wrong/is happening?

Ok. As it seems, it's a Windows/ Git issue.
This is the text with JSON.stringify
console.log
"type Query {\n updateTest(input: UpdateOne!): Int!\n}\n\ninput UpdateOne {\n \"\"\"The id of the record to update\"\"\"\n id: ID!\n\n \"\"\"The update to apply.\"\"\"\n update: FakeUpdateOneType!\n}\n\ninput FakeUpdateOneType {\n name: String!\n}\n"
at Object.<anonymous>.exports.expectSDL (packages/query-graphql/__tests__/__fixtures__/index.ts:22:11)
console.log
"type Query {\r\n updateTest(input: UpdateOne!): Int!\r\n}\r\n\r\ninput UpdateOne {\r\n \"\"\"The id of the record to update\"\"\"\r\n id: ID!\r\n\r\n \"\"\"The update to apply.\"\"\"\r\n update: FakeUpdateOneType!\r\n}\r\n\r\ninput FakeUpdateOneType {\r\n name: String!\r\n}\r\n"
If Git for Windows isn't set up correctly, it will add /r/n as line breaks when cloning a repo. If the project was developed in anything other than Windows, then text comparisons with toEqual that have line breaks in them will fail. Too bad Jest doesn't say something like "mismatched line breaks" or show the escaped characters.
To fix this, I installed Git for Windows (I needed to upgrade anyway) with this option, which sets core.autocrlf to "input".
