 Hi,
 st_astwkb is not returning a valid geometry. As an example:

 ```select st_isvalidreason(st_geomfromtwkb(st_astwkb(st_geomfromgeojson('{
         "type": "Polygon",
         "coordinates":
 [[[2.1776390993201,41.3722988965004],[2.17763909886103,41.37229889631543],[2.17763909900003,41.3722988970001],[2.1820804568871637,41.37027921005133],[2.18208045654673,41.3702792096251],[2.1776390993201,41.3722988965004]]]
       }'))))
 ```
