Well, it encountered a GRANT statement like, e.g.

GRANT UPDATE(aField) on aTable TO SRMAX

and it discovered that aField doesn't exist in aTable. A likely cause
could be that the column is actually defined as "aField" - quoted
identifiers and case-sensitive.

It is.

Open the database with a tool that can show you the system tables and
inspect the privileges in RDB$USER_PRIVILEGES for SRMAX. Or just use a
query to get at the data you need to look at:

select
rdb$grantor, rdb$user,
rdb$relation_name,
rdb$field_name from rdb$user_privileges
where rdb$user = 'SRMAX'
and rdb$relation_name not starting with 'RDB$'
and rdb$field_name is not null
