Partman maintenance function issue

Hello Folks ,

We are moving from native partitioning to partman based partitioning. We
used this doc to migrate the existing set to partman
https://github.com/pgpartman/pg_partman/blob/master/doc/migration_to_partman.md

All the old partitions are renamed and new partitions were also created in
the initial setup with partman.create_parent function with the premake
values. Now we want to run maintenance to create the next set of partitions
for the future .
We are trying to run the command

select partman.run_maintenance(

p_parent_table := '<schema_name>.<table_name>');

This command gives error

SQL Error [P0001]: ERROR: zero-length delimited identifier at or near """"
CONTEXT: PL/pgSQL function partman.run_maintenance(text,boolean,boolean)
line 374 at EXECUTE
DETAIL:
HINT:
Where: PL/pgSQL function partman.run_maintenance(text,boolean,boolean)
line 408 at RAISE
If someone can help understand the cause of the error ,it would be
helpful for debugging.
