5.19.2
(fix): Fix the OAuth token provider crashing with “Access token not present in OAuth response”
when the token response does not include a refresh token. Client-credentials token
responses often omit refresh_token; the provider now treats it as optional instead
of raising.
5.19.1
(fix): OAuth client credentials token requests now send grant_type: "client_credentials"
when the token endpoint declares a non-literal grant_type request property. The
property is synthesized in the token request and is no longer surfaced as a
user-supplied option.
