Current behavior

Expected behavior

I should be able to use the externally-referenced image as an example value for my endpoint (provided that Swagger UI is able to reach the resource).

Additional context or thoughts

#5427.

I don't know if this is the appropriate issue, but instead of binary image, I simply want external JSON to display. Is this already planned?

I build my self a quick hack, that works for me for now

Same for me, would like to embed external json, but it's simply empty...

[matrunchyk]

@shockey Thank you for opening this issue! Do you know an approx. ETA for this?

[simundev]

I have the same problem. I prefer to keep my examples in external .json files (same with models) so as not to clutter the spec itself too much. Any idea where this is in the priority stack please?

[yoanncouillec]

Same here. externalValue does not display the pointed json

[verilog15]

Same here. externalValue does not work for me. It displays an empty field. Was there a 3.0.x OpenAPI version which it worked? Or is there some other way to do it without setting it manually?

[teffi]

Echoing this issue. Would be helpful to finally have externalValue work with example.
