Districts' names with state names as CSV with Overpass API

I am looking district names of India with state names as CSV format. I tried to write an overpass query but it is not working. Please let me know what I am doing wrong. Is there any other simple query also. I am looking only from Overpass API not from any other data provider.

[out:csv(::type,::id,admin_level,name,"name:en","country","admin_level_4_name")];

rel["name:en"="India"]->.rel;
map_to_area->.a;

(
    rel[admin_level=4](area.a)->.admin_level_4;
    rel[admin_level=5](area.a)->.admin_level_5;
    foreach.admin_level_5(
        out center ->.ctr;
        .ctr is_in->.admin_level_4_relation;
        .admin_level_5 set admin_level_4_name = .admin_level_4_relation["name"];
        out;
    );
);

out;

Update 1:

I am adding here the overpass-turbo error:

An error occurred during the execution of the overpass query! This is what overpass API returned:

Error: line 10: parse error: Invalid parameter for print: "->"
Error: line 10: parse error: Invalid parameter for print: "."
Error: line 10: parse error: Invalid parameter for print: "ctr"
Error: line 12: parse error: ';' expected - 'set' found.

Link to overpass-turbo for this routine.

Update 2:

As per DaveF suggestions here is the modified the query. Now not able to make out how to set admin_level 4 names to admin_level 5.

[out:csv(::type,::id,admin_level,name,"name:en","country","admin_level_4_name")];
rel["name:en"="India"];
map_to_area->.a;
(
    rel[admin_level=4](area.a)->.admin_level_4;
    rel[admin_level=5](area.a)->.admin_level_5;
    foreach.admin_level_5(
        out center;
        is_in->.admin_level_4_relation;
        // not able to make out how to set level 4 name to level 5 relation
        convert rel ::=::; 
        out;
    );
 );
