boto3 lambda script to shutdown RDS not working

Question

I'm just starting out with boto3 and lambda and was trying to run the below function via Pycharm.

import boto3

client = boto3.client('rds')

response = client.stop_db_instance(
    DBInstanceIdentifier='dummy-mysql-rds'
)

But i receive the below error:

botocore.errorfactory.DBInstanceNotFoundFault: An error occurred (DBInstanceNotFound) when calling the StopDBInstance operation: DBInstance dummy-mysql-rds not found.

Do you know what may be causing this?

For the record, I have the AWS toolkit installed for Pycharm and can run simple functions to list and describe ec2 instances and my AWS profile has admin access.

Answer 1

By explicitly defining the profile name the below function now works via Pycharm. Thank you @OleksiiDonoha for your help in getting this resolved.

import boto3
rds = boto3.setup_default_session(profile_name='dev')
client = boto3.client('rds')

response = client.stop_db_instance(
    DBInstanceIdentifier='dev-mysql-rds'
)
