I have successfully created the catalog using the following Flink SQL, and my local REST service has also received the request.

Flink SQL> CREATE CATALOG paimon_rest_test_metalake.paimon_rest_catalog

WITH (
'type' = 'paimon',
'uri' = 'http://localhost:8080/paimon-rest/',
'metastore' = 'rest',
'warehouse' = 'paimon_rest_test_metalake.paimon_rest_catalog',
'rest.client.content-type' = 'application/json',
'token.provider' = 'bear',
'token' = 'random_token_123456_for_test'
);
[INFO] Execute statement succeeded.

switch to catalog paimon_rest_test_metalake.paimon_rest_catalog:

Flink SQL> use catalog paimon_rest_test_metalake.paimon_rest_catalog;
[INFO] Execute statement succeeded.

create table events:
Flink SQL> CREATE TABLE events (

event_id INT,
user_id INT,
event_type STRING

);
[ERROR] Could not execute SQL statement. Reason:
org.apache.paimon.rest.exceptions.RESTException: Unable to process: Content-Type 'text/plain;charset=UTF-8' is not supported
