'Permission denied for relation stl_load_errors on Redshift Serverless

I use Amazon Redshift Serverless and Query editor(v2) and I'm having trouble with user permissions. The following error occurred when importing data(.csv) in S3.

ERROR: Load into table 'x' failed. Check 'sys_load_error_detail' system table for details.

Therefore, I executed the command Select * From stl_load_errors to check the error, but it did not work well.

ERROR: permission denied for relation stl_load_errors

I checked my user permissions using select * from pg_user;and they are presented as follows. However, I don't see any problem, what is the problem? (I use hoge.)

usename	usesysid	usecreatedb	usesuper	usecatupd	passwd	valuntil	useconfig
rdsdb	1	true	true	true	********	infinity	NULL
hoge	101	true	true	false	********	NULL	NULL

I have tried to look at the query in the Amazon Redshift Serverless (Preview) dashboard under "Query and Database Monitoring", but could not find any details about the error.

What should I do?
