video-on-demand-on-aws: MediaInfo can't get the Object Key and throwing a signing method error

Hi,

I’m not sure what’s going on but i keep getting this error while executing the mediaInfo Lambda Function. <Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message><AWSAccessKeyId>********************</AWSAccessKeyId><StringToSign>AWS4-HMAC-SHA256

which fails the function while trying to retrieve the uploaded file info with a null exception

[ERROR] TypeError: 'NoneType' object is not subscriptable Traceback (most recent call last): File "/var/task/lambda_function.py", line 157, in lambda_handler raise err File "/var/task/lambda_function.py", line 124, in lambda_handler tracks = json_content['media']['track']

I tried different filenames and extensions .mp4, .mov but i always get the same error any help is appreciated

Thanks, -Kader

so i think i got it to work doing the following in that same file (lambda_function.py) after the imports i added AWS_REGION = os.getenv(‘AWS_DEFAULT_REGION’, ‘eu-west-1’)

in def get_signed_url(bucket, obj): // line 102 i changed s3_client = boto3.client(‘s3’) to s3_client = boto3.client(‘s3’, endpoint_url=f’https://s3.{AWS_REGION}.amazonaws.com’, region_name=AWS_REGION)

then zip the function, upload, choose Python 3.7 … btw 3.8 does not work for me

@aloussayef The issue is with the version boto3, and an intermittent one. I have 2 version of VOD running in my account one with the issue and one without. I fixed the error by removing the version of boto3 shipped with the code, defaulting to the version that is installed in lambda.

please try:

download the repo.
cd source mediainfo
chmod +x bin/mediainfo
zip -rq …/lambda.zip *
navigate to the lambda console and upload the zip file to replace the function.

Let me know if this works, we’ll continue to look at the problem and get a fix out to the repo.
