TypeORM - PostGIS use custom feature in query - postgis

Question

I have a project where I need to check inside which municipalities a certain road is inside. In order to do so I check this using the ST_Intersects function provided by PostGIS.
The problem that I am facing is that I keep on getting errors when using the roads in the querybuilder of typeorm.
My first attempt gave me the following error QueryFailedError: ST_Intersects: Operation on mixed SRID geometries (MultiPolygon, 4326) != (LineString, 0) at new QueryFailedError:
const municipalities = await getConnection()
.getRepository(Municipality)
.createQueryBuilder('municipality')
.where('ST_Intersects(municipality.polygon, :lineString)', { lineString: feature.geometry })
.getQueryAndParameters()
Then I tried to fix this by setting the CRS of the Linestring using ST_SetSRID function that is also provided by PostGIS. But this gives me the following error QueryFailedError: function st_setsrid(unknown, integer) is not unique:
const municipalities = await getConnection()
.getRepository(Municipality)
.createQueryBuilder('municipality')
.where('ST_Intersects(municipality.polygon, ST_SetSRID(:lineString, 4326))', { lineString: feature.geometry })
.getMany()
I have also tried to transfer the Geojson object using ST_GeomFromGeoJSON function in PostGIS. But this gives me the following error: QueryFailedError: quoted object property name expected (at offset 1):
const municipalities = await getConnection()
.getRepository(Municipality)
.createQueryBuilder('municipality')
.where('ST_Intersects(municipality.polygon, ST_GeomFromGeoJSON(:lineString))', { lineString: feature.geometry.coordinates })
.getMany()
I have tried to see if the problem was when inserting the linestring into the query. I did this by using the getQueryAndParameters return function of typeorm:
[
'SELECT "municipality"."uuid" AS "municipality_uuid", "municipality"."name" AS "municipality_name", ST_AsGeoJSON("municipality"."polygon")::json AS "municipality_polygon" FROM "municipality" "municipality" WHERE ST_Intersects("municipality"."polygon", ST_SetSRID($1, 4326))',
[ { type: 'LineString', coordinates: [Array] } ]
A Linestring object in looks as follows:
{
type: 'LineString',
coordinates: [

Answer 1

I have found an answer. ST_GeomFromGeoJSON was indeed the wright function to use in order to inject a GeoJSON object into the query. But I had accidentally used the coordinates instead of the full GeoJSON object.
So the solution is:
const municipalities = await getConnection()
.getRepository(Municipality)
.createQueryBuilder('municipality')
.where('ST_Intersects(municipality.polygon, ST_GeomFromGeoJSON(:lineString))', { lineString: feature.geometry })
.getMany()
