im getting this error when installing

failed to pull images of the stack: service "db" refers to undefined volume db: invalid compose project

if i remove the db: string under the volumes on the mariadb it will pull and start but then lychee says it cant connect to maria db but i left everything the same and inputed the ip of the container runnin mariadb it created and still not working?

Any ideas by chance i am trying to set this up so i can create a wedding album so i can create a share link for everyone to upload the wedding pictures for my wedding coming up so its like a photographer free if i can get this to work i had it running off a different database but it just wouldnt work as the pics were just broken thumbnails showing and the diagnostics was complaing about the url since i am using NPM to send to secure https

I am getting the same as @Baltimorepc @dnburgess

Also, I am getting 502 Bad Gateway nginx
