AWS SDK / DynamoDB Example doesn't work #116

Open orgsofthq opened 2 years ago

orgsofthq commented 2 years ago

The documentation at https://deno.com/deploy/docs/tutorial-dynamodb/ gives an example of using the AWS SDK on Deploy imported via skypack.

When deployed, however, it doesn't work - giving a 502 Bad Gateway error and an error message is logged:

Error: [Package Error] "@aws-sdk/util-utf8-browser" no dependency version info found. (Imported by "@aws-crypto/sha256-browser").
    at https://cdn.skypack.dev/error/unknown:@aws-sdk/util-utf8-browser?from=@aws-crypto/sha256-browser:13:7

I've tried using esm/jspm/deno.land/skypack imports with various versions/configs. While it runs fine locally w/ Deno, the AWS SDK seems to always have an import related error when run on Deploy.

I also tried it out today and failed - but I got a different error:

TypeError: that.write is not a function
