I'm getting a Boto3 InvalidParameterException while running the lambda function. I'm trying to find out a way to handle this exception.
I came across the below solution:
from boto.exception import BotoServerError
class InvalidParameterException(BotoServerError):
pass
I'm using python3 and understood that boto is deprecated now and is replaced by boto3. But i could not find an equivalent solution in boto3.
Can anyone help me out with this ?
As boto is deprecated all the modeled exceptions are available on the client. You can look it up same in the API docs as well , basically the code for the boto3 is straight away generated from the APIs. Earlier approach with boto was hard coded stuff and writing code for the same.
As you can see here
For example
import boto3
from botocore.exceptions import ClientError
def get_secret():
secret_name = "MySecretName"
region_name = "us-west-2"
session = boto3.session.Session()
client = session.client(
service_name='secretsmanager',
region_name=region_name,
)
try:
get_secret_value_response = client.get_secret_value(
SecretId=secret_name
)
except ClientError as e:
if e.response['Error']['Code'] == 'ResourceNotFoundException':
print("The requested secret " + secret_name + " was not found")
elif e.response['Error']['Code'] == 'InvalidRequestException':
print("The request was invalid due to:", e)
elif e.response['Error']['Code'] == 'InvalidParameterException':
print("The request had invalid params:", e)
elif e.response['Error']['Code'] == 'DecryptionFailure':
print("The requested secret can't be decrypted using the provided KMS key:", e)
elif e.response['Error']['Code'] == 'InternalServiceError':
print("An error occurred on service side:", e)
