Cannot render images without file extensions

[ianjamieson]

I am using version 4.2 with no modifications.

Given an image in S3:

https://bucket.s3-region.amazonaws.com/imageWithNoExtension

I cannot access this image in via cloudfront: https://uniqueId.cloudfront.net/imageWithNoExtension

I get the error:

{
"status": 400,
"code": "DecodeRequest::CannotDecodeRequest",
"message": "The image request you provided could not be decoded. Please check that your request is base64 encoded properly and refer to the documentation for additional guidance."
}

Also, I cannot use the Thumbor style syntax to resize this image: https://uniqueId.cloudfront.net/fit-in/100x100/imageWithNoExtension

I get this error:

{
"status": 400,
"code": "RequestTypeError",
"message": "The type of request you are making could not be processed. Please ensure that your original image is of a supported file type (jpg, png, tiff, webp) and that your image request is provided in the correct syntax. Refer to the documentation for additional guidance on forming image requests."
}

When you parseRequestType, matchDefault.test(path) is true:

https://github.com/awslabs/serverless-image-handler/blob/19cbc3ce759d7c8d8ddc35081972d7ac1daf0c71/source/image-handler/image-request.js#L207-L233

And subsequently when attempting to decodeRequest:

https://github.com/awslabs/serverless-image-handler/blob/19cbc3ce759d7c8d8ddc35081972d7ac1daf0c71/source/image-handler/image-request.js#L242-L255

That try block fails and throws the error.

What I am hoping to achieve is that if my file exists (without a file extension) in S3 then we can still serve that image via cloudfront.

Hi @ianjamieson , and thanks for contacting us.
It might be related to #169 as well, so we would think about it.

Hey @beomseoklee - yeh it looks similar, I have subscribed to the other thread.

I made this for me from latest version. It handles files without extensions.

You can try and see if it works for you. It's based on 4.2 version

[ianjamieson]

@Karlen92 - that's great thank you. Are there significant changes? How about making a PR on this repo or forking this repo?

[Karlen92]

@ianjamieson changes are a few lines, but I believe in the latest version now it's fixed

[ianjamieson]

Thanks @Karlen92

Ran into this bug as of release 5.1, still not fixed.

We've added limited support for files without extensions in v5.2.0. Any image filters that use Amazon Rekognition (content moderation and smart cropping) will not work with files that do not have an extension.
