encodedSlash is not supported in filters

It seems that the Balena API doesn’t properly support URL-encoded API requests which is a real bummer since most OSS and other UI tools for making API requests encode URLs by default as it is the web standard. There has been a long-standing issue open for this for quite sometime now on Github and older forum posts:

My specific problem is that I can not expand/select multiple fields of an API request due to the ‘,’ being URL-encoded but the API not supporting this and I have no way of sending this unencoding through the UI tool I am using
