TypeError: Attempting to change enumerable attribute of unconfigurable property with PhantomJS

[sridharrajagopal]

Hi,

I'm trying to use AWS SDK for Javascript in a browser environment, but with PhantomJS.

PhantomJS chokes with the following error stack with the aws-sdk-js

https://sdk.amazonaws.com/js/aws-sdk-2.24.0.min.js:40 in defineProperty

I'm referencing the corresponding issue in phantomjs github - ariya/phantomjs#13895

Any help is greatly appreciated!

Thanks,

What version of phantomJS are you using? Travis currently runs anytime a PR is submitted to this SDK, and one of the steps is running the browser sdk tests using phantomjs 2.1.14.

@chrisradek

I'm running phantomjs 2.1.1
Can you tell me where I can find 2.1.14?

I get mine from https://bitbucket.org/ariya/phantomjs/downloads/?tab=downloads and only see 2.1.1 there.

Thanks,
Sridhar

Here is such a call that phantomjs complains about -

        // s3.upload({
        //     Key: "file.png",
        //     Body: buf,
        //     ACL: 'public-read',
        //     ContentType: 'image/png'
        // }, function(err, data) {
        //     if (err) {
        //         return alert('There was an error uploading your chart: ', err.message); 
        //     }
        //     alert('Successfully uploaded chart.');
        // });

The other one was a dynamodb query

Both of these work in a "regular" browser.

Btw, I checked that 2.1.14 from npm is indeed version 2.1.1 that I got directly from the phantomjs github.

Hi i had the same error message using the AWS browser SDK in Apache Cordova, whenever i tried to invoke aws-lambda functions. Apparently it was due my restrictive Content-Security-Policy (albeit allowing for the aws-sdk), since i was able to get it running by using the wildcard (for development).

I have yet to figure out, which domain is specifically needed for my lambda-invocations, so feedback is appreciated, but i wanted to get this out, because i never would have guessed the cause from the error message alone and maybe it's also the cause for OP's problem.

Any updates or feedback on this issue?

Much appreciated!

Is this still an outstanding issue? Since you raised this issue, development on PhantomJS has stopped.

There are some more recent alternatives that would likely be a better fit for you long-term as they are being developed.

This issue has been automatically closed because there has been no response to our request for more information from the original author. With only the information that is currently in the issue, we don't have enough information to take action. Please reach out if you have or find the answers we need so that we can investigate further.

[sridharrajagopal]

Yes, this is still an outstanding issue for me, though I haven't tried it again since I reported my issue above as it didn't work.

I can look into alternatives for PhantomJS as you suggest.

[srchase]

As PhantomJS is no longer supported, I'm going to close this issue. Let us know if you have any issues using the SDK with the current alternatives.
