Random image suite failures

johnsickels commented 3 years ago

We see the sporadic failure:

But a rerun, or a manual check to the image is fine.

My suspicion is somewhere around how much of the image loads:

An image scenario will load only the first 512 bytes of the image, which includes the meta data that we need to assert things like height and width.

The first 512 bytes of the image is where the metadata lives. So that's why we only need to load 512. Would have to investigate what is being returned, although it looks like it's not getting anything

We started to log the response if the mime type is not what we expect and are getting this:

  _httpResponse: HttpResponse {
    body: '',

The library we use does not support .jpg. I'm struggling to find an example gallery that does not use .jpg
