KeyError:'1,2' running Postgresql regexp_match() in Jupyter Notebook

I am using Jupyter notebook to run postgresql. Python, postgres, pips and Jupyter are all up to date. I have been able to load sql with

%load_ext sql

and connected to the postgres database with

%sqlpostgresql://postgres:postgres@localhost/analysis

Table was created and loaded a csv loaded successfully with

%%sql
CREATE TABLE crime_reports (
 crime_id bigserial PRIMARY KEY,
 date_1 timestamp with time zone,
 date_2 timestamp with time zone,
 street varchar(250),
 city varchar(100),
 crime_type varchar(100),
 description text,
 case_number varchar(50),
 original_text text NOT NULL
);
COPY crime_reports (original_text)
FROM 'C:\YourDirectory\crime_reports.csv'
WITH (FORMAT CSV, HEADER OFF, QUOTE '"');

However, this code

%%sql
SELECT crime_id,
 regexp_match(original_text, '\d{1,2}\/\d{1,2}\/\d{2}')
FROM crime_reports;

runs successfully in pgAdmin, returning dates but in the Jupyter notebook I get this error instead:

KeyError: '1,2'

I have tried trusting the Notebook and still getting same error.
