ERROR: invalid string in message when querying into a PostgreSQL database

Question

I have this query:

SELECT "user".id AS user_id,
   "user".is_verified AS user_is_verified, 
   "user".name AS user_name, 
   "user".nickname AS user_nickname, 
   "user".password AS user_password, 
   "user".birthdate AS user_birthdate, 
   "user".food_restrictions AS user_food_restrictions, 
   "user".email AS user_email, 
   "user".telephone AS user_telephone, 
   "user".address AS user_address, 
   "user".shirt_size AS user_shirt_size, 
   "user".type AS user_type, 
   "user".created_at AS user_created_at, 
   "user".updated_at AS user_updated_at, 
   "user".image AS user_image, 
   "user".is_image_url AS user_is_image_url, 
   "user".code AS user_code, 
   "user".terms_accepted AS user_terms_accepted, 
   "user".recive_mails AS user_recive_mails, 
   "user".lleidacoins_claimed AS user_lleidacoins_claimed, 
   "user".token AS user_token, 
   "user".refresh_token AS user_refresh_token, 
   "user".verification_token AS user_verification_token, 
   "user".rest_password_token AS user_rest_password_token, 
   hacker.user_id AS hacker_user_id, 
   hacker.banned AS hacker_banned, 
   hacker.github AS hacker_github, 
   hacker.linkedin AS hacker_linkedin, 
   hacker.cv AS hacker_cv, 
   hacker.studies AS hacker_studies, 
   hacker.study_center AS hacker_study_center, 
   hacker.location AS hacker_location, 
   hacker.how_did_you_meet_us AS hacker_how_did_you_meet_us
FROM hacker_event_accepted, 
     "user" JOIN hacker ON "user".id = hacker.user_id
WHERE 1 = hacker_event_accepted.event_id 
      AND hacker.user_id = hacker_event_accepted.user_id

psql shows this error:

ERROR: invalid string in message

I was trying this in a fastapi but also trying the query directly on a psql connection fails either, I have searched and postgresql has a max query limit but is 1600 columns and also if I remove 4 columns from the select the query works perfectly
