@NataliaB, A few remarks:
- You are using a File field and according the docs:
The
filefield is intended to be used by configuration , theme , and plugins blueprints, NOT page blueprints . For pages, you should use the existingpagemediafield and then utilize the filepicker field to select the files. - When using a File field,
{{page.header.custom.coverImage}}is indeed an array. Have a look at your *.md {{ page.content }}should be{{ page.content | raw }}<img src= " {{page.header.custom.coverImage}} " />
should be:
<img src= "{{ page.url }}/{{ page.header.custom.coverImage }}" />
or maybe:
{{ (page.media.images|first).html | raw }}
but why show on page with
I’m afraid I do not understand you last remark.
Maybe just a matter proper formatting using triple backticks (```) and < instead of <.
