"Exception on token flow - unsupported_grant_type_for_pkce: Grant type password is not supported. PKCE only supports authorization code flow: no thrown error". This is the system log message after I sent a request to get the refresh token from Postman . I has created new rest user with web service access only, grant_type is also "password". I found that there was no post or same issue related this error.

Hi @Hai Nguyen Duu and @PLaxmiPrasanna, the Grant type for non interactive user can only be JWT Bearer or Client Credentials see https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0818290.

A similar error string can happen if you are missing the property
glide.oauth.inbound.client.credential.grant_type.enabled
