underpass | Ruby library that translates Overpass API responses

I'm trying to upload files with Api Platform and Vich Uploader Bundle. When I send POST request with multipart/form-data and Id of the entity to attach image file to, I get 200 response with my entity. But uploaded file doesn't uploads to destination directory and it's generated filename doesn't persists. No errors, no any clues, no idea.

Here is my code:

I have a DB table name is the product. when I query (eloquent) to that table return collection object with all the fields. but I access the banner_image field every time return a null value. but I can access the other variables in that collection working fine. If I Defining An Accessor, the issue is solved. I want to know about, whats the issue only for one variable.

DD to eloquent collection

I am working on creating a form to send a styled email, everything worked fine until I started to add IDs to my html elements inside of my php variable. Is there a reason this does not work? I have tested the html code and it works fine on its own, but when put into a php variable, the page will not run. I looked at a few other posts and they said to just add IDs like I have, but it does not work. Any ideas why?

I have a question not on spatstat but on use and limitation of spatsat.

During the calculation of metrics like pcf and k function equivalents on linear networks, a shortest path distance is used instead of euclidean distance. I have the spatsat book from 2015 and I remember reading somewhere in the text that the shortest path calculation on networks is not sensitive to grade separations like flyover, bridges, underpass and therefore caution should be exercised in selecting the study area or be aware of this limitation while interpreting results.

Is there any publication that discusses this limitation of grade separation in detail and may be suggesting some workarounds? Or limitations of network equivalents in general?

Thank you
