## 4.57.3

**`(fix):`** Handle optional access tokens in OAuth token provider by raising `RuntimeError`
when the token is `None`. Fix wire test setup to use `client_id`/`client_secret`
for OAuth client credentials and expect 2 requests when testing the token endpoint.

## 4.57.2

**`(fix):`** Fix path-based pagination to pass the next page path as `path=` instead of `url=`
in the generated HTTP client request call.
