ERROR: input of anonymous composite types is not implemented

I am really confused. I have this postgis query :

with 
f as ( SELECT
    ST_AsGeoJSON(p.geompos)::json As geometry, 
    row_to_json((p.id_client, p.design_site, p.adresse)) As properties
    FROM sites p
    where p.id_client ilike '1%'

),  
fc as ( SELECT 
       'FeatureCollection' As type, 
       array_to_json(array_agg(f)) As features 
       FROM f 
      ) 
SELECT row_to_json(fc) FROM fc

It work fine. But when I use a condition :

where p.id_client not ilike '1%'

I got the error message :

ERROR:  input of anonymous composite types is not implemented 
SQL state: 0A000

I think that some geometry data make problem. How can I fix this? I have more than 22000 rows and this is why I can not find the row who make the problem. and this is the ddl of the sites table :

CREATE TABLE IF NOT EXISTS public.sites
(
    idsite serial,
    id_client character varying(8) COLLATE pg_catalog."default",
    design_site character varying(1024) COLLATE pg_catalog."default",
    adresse character varying(1024) COLLATE pg_catalog."default",
    geompos geometry,
    CONSTRAINT pk_sites PRIMARY KEY (idsite),
    CONSTRAINT fk_sites_associati_ref_clie FOREIGN KEY (id_client)
        REFERENCES public.ref_client (id_client) MATCH SIMPLE
        ON UPDATE RESTRICT
        ON DELETE RESTRICT
)
