Generated presigned URLs do not work in the browser

[tmathern]

Expected Behaviour

Presigned URLs generated by the aio-lib-files library should be usable directly in the browser as is. If I used the library in a wrong way (see below), would there be a way to support this usage? (Which comes near to https://github.com/adobe/aio-lib-files/issues/59).

Actual Behaviour

Presigned URLs generated by the aio-lib-files library cannot be used. For instance when trying with the browser, I get this error:

<Error>
<Code>BlobNotFound</Code>
<Message>The specified blob does not exist. RequestId:92974b1e-d01e-0114-6272-05e910000000 Time:2021-02-17T21:21:06.1462572Z</Message>
</Error>

Reproduce Scenario (including but not limited to) & Sample Code that illustrates the problem

Run this piece of code. The generated URLs won't work:

        const filesLib = require('@adobe/aio-lib-files');

        // generate presigned-urls for input and output
        const files = await filesLib.init({
            azure:
            {
                storageAccount: process.env.AZURE_STORAGE_ACCOUNT,
                storageAccessKey: process.env.AZURE_STORAGE_KEY,
                containerName: process.env.AZURE_STORAGE_CONTAINER,
            }
        });

        const readUrl = await files.generatePresignURL("./test/files/newton.dn", 
            { 
                expiryInSeconds: 86400, 
                permissions: 'r'
            }
        );
        console.log(readUrl);

        const writeUrl = await files.generatePresignURL("./test/files/newton.dn", 
            { 
                expiryInSeconds: 86400, 
                permissions: 'rwd'
            }
        );
        console.log(writeUrl);

If I used the library in a wrong way, would there be a way to support this usage, so I can use aio-lib-files for all my needs? (Which comes near to https://github.com/adobe/aio-lib-files/issues/59 also, I think).

Steps to Reproduce

Hi @tmathern , let's ask @sandeep-paliwal and @moritzraho for more guidance.

[sandeep-paliwal]

Hi @tmathern , I guess the file is not present in the file storage for which the URLs are being generated. You will have to create the file using the write operation and then it can be shared using presign-URLs. Just add following line before generating the URL and see if this works for you. await files.write('./test/files/newton.dn', '<h1>Test file url issue</h1>')

Hi @tmathern ! Did @sandeep-paliwal 's answer help you solve your issue?

[tmathern]

@meryllblanchet It helped. I'll close this.
