hasAnyRole documentation description doesn't seem to work

[darrylhein]

In the documentation is says @=hasAnyRole accepts a set of string parameters. But when trying with strings, I get the error:

Overblog\\GraphQLBundle\\Security\\BaseSecurity::hasAnyRole(): Argument #1 ($roles) must be of type array, string given, 
called in /app/cache/dev/overblog/graphql-bundle/__definitions__/ExternalMutationType.php on line 44

If I change it to an array, it seems to work:

@=hasAnyRole(["ROLE_ADMIN", "ROLE_BIG_TIME"])

Should the documentation be correct to say it's an array of strings? hasAnyPermission seems to work this way.

# old:
@=hasAnyRole('ROLE_API', 'ROLE_ADMIN')
# new:
@=hasAnyRole(['ROLE_API', 'ROLE_ADMIN'])

Happy to do it, but I wanted to make sure I'm not just misunderstanding.
