Specifying ConnectionProperties When Creating New Connection in Boto3 - python-3.x

Question

I'm trying to create a connection using a boto3 python script. It's a connection to a mysql database on an ec2 instance. I'm using the script below. I'm getting the error message below. I'm not sure what I'm missing. I've used similar scripts to create glue crawlers without issue. I'm pretty much following the boto3 documentation except I added username and password in the ConnectionProperties. I'm not sure if that's correct. Can someone please let me know if I'm doing this right, or else what I need to fix in my code?
code:
# create new connection
response = client.create_connection(
ConnectionInput={
'Name': 'tst_scrpt',
'ConnectionType': 'JDBC',
'ConnectionProperties': {
'string': 'jdbc:mysql://dataxxx:3306/disxxx',
'username':'root',
'password':'ip1k5PNCxxxxx'
}
,
'PhysicalConnectionRequirements': {
'SubnetId': 'subnet-0436167b7cbxxxx',
'SecurityGroupIdList': [
'sg-02c3f45ce51exxxxx'
]
}
}
)
Error:

Answer 1

I had the ConnectionProperties wrong. replace 'string' with 'JDBC_CONNECTION_URL'. The correction is below.
'ConnectionProperties': {
'JDBC_CONNECTION_URL': 'jdbc:mysql://dataxxx:3306/disxxx',
'username':'root',
'password':'ip1k5PNCxxxxx'
}
