Media is typed as string | Media
I am using the auto generated types from Payload and a media collection for several upload fields. As I am typing my component props the media properties like e.g. "icon" is typed as string | Media which leads to error when referring to Media attributes like icon.filename because that does not exist on strings of course. It's a pain to cast all of the media types to be Media. To me the typing does not make sense so I am questioning if the mistake is on my side or there is a good reason for it to be string | Media.

logo?: string | Media;

Hi
@690590499202924574,
That is not a mistake on your part. We have had a lot of discussion around the best way to type relationships and uploads. The complication here is that when a document is read the population is dynamic based on the
depthparameter. Since there are times when the depth is 0, you can expect to get a string with the
idinstead of the Media object.
There have been some ideas come out about how this could be improved in Github discussions.
https://github.com/payloadcms/payload/discussions/1563I added a link if you're interested in that, several comments talk about workaround to the depth problem.
Oh and one other reason that a relationship or upload can be a string is because of access control. Suppose a user can read a parent document but is not allowed
readaccess to the related doc. That relationship will not be populated and is left as a string.
Alright I already thought that this (edit: depth) might be the reason for it. I will give it a read later that day and hopefully I ll come up with a better solution than type casting it in the frontend. Thank you a lot for the explanation
