"INVALID_CURSOR_ARGUMENTS" from Github graphql API - api

Question

I am using the following query:
query myOrgRepos {
organization(login: "COMPANY_NAME") {
repositories(first: 100) {
edges {
node {
name
defaultBranchRef {
target {
... on Commit {
history(after: "2021-01-01T23:59:00Z", before: "2023-02-06T23:59:00Z", author: { emails: "USER_EMAIL" }) {
edges {
node {
oid
}
}
}
}
}
}
}
}
}
}
}
But with accurate names for the orginization and emails, and am persistantly getting the following error for every repo.
{
"type": "INVALID_CURSOR_ARGUMENTS",
"path": [
"organization",
"repositories",
"edges",
20,
"node",
"defaultBranchRef",
"target",
"history"
],
"locations": [
{
"line": 10,
"column": 29
}
],
"message": "`2021-01-01T23:59:00Z` does not appear to be a valid cursor."
},
If I remove the after field, it works just fine. However, I kind of need it. Acording to all the docs that I have read both after and before take the same timestamp. Can't tell where I am going wrong here.
I have tried:
to narrow the gap between before and after
return only a single repository
remove after (works fine without it)
