django - Properly catch boto3 Errors -


i developing django app communicates several amazon web services.

so far having trouble dealing , catching exceptions thrown boto3 client. doing seems unnecessarily tedious:

example:

client = boto3.client('sns') client.create_platform_endpoint(platformapplicationarn=sns_app_arn, token=token)

this might throw botocore.errorfactory.invalidparameterexception if e.g. token bad.

client.get_endpoint_attributes(endpointarn=endpoint_arn)

might throw botocore.errorfactory.notfoundexception.

first, can't find these errors anywhere in code, generated somewhere. bottom line: can't import , catch usual.

second, found 1 way catch error here using:

try:     # boto3 stuff except botocore.exceptions.clienterror e:     if e.response['error']['code'] == 'notfound':         # handle exception     else:         raise e

but have remove exception part of error name. seems random , have no clue whether remove error in botocore.exceptions.paramvalidationerror if wanted catch one. it's hard generalize.

another way catch error using boto3 client object got:

try:     # boto3 stuff except client.exceptions.notfoundexception e:     # handle exception

this seems cleanest way far. don't have boto3 client object @ hand want catch error. still trying things out, it's guess work.

does know how boto3 errors supposed handled?

or can point me towards coherent documentation mentions errors above? thanks
