If Image Target is too large, ES throws a status code 413
I tried publishing a HoloLens Image Target experience, and the publishing failed. The logs showed the following:
[2020-05-11T17:00:18.409Z] error: [twx-studio:ves-publish:1589216415170:AR_Templater_Hololens] Failed to upload to the Experience Service. null[2020-05-11T17:00:18.409Z] error: [twx-studio:projectHelper] publishTask error for project AR_Templater_Hololens { statusCode: 413, message: '{"message":"long running target generation process terminated","errorCode":"","error":{}}'}
The image I was trying to use as an Image Target was 2.9 MB, and 7068x7068. I made the image smaller to be 7"x7" and less than 1 MB, and then the project published successfully.
Studio should show a proper warning/error if you try using an Image Target that's too large.
