Your problem is that you're trying to use the variable filestoser as a filename, but it's not: it's the result of the find task. If you take a look at the output of your debug task you'll see something like this:
TASK [debug] **********************************************************************************
ok: [localhost] => {
"filestoser": {
"changed": false,
"examined": 44,
"failed": false,
"files": [
{
"atime": 1554394659.885133,
"ctime": 1554394659.885133,
"dev": 45,
"gid": 21937,
"gr_name": "lars",
"inode": 172846,
"isblk": false,
"ischr": false,
"isdir": false,
"isfifo": false,
"isgid": false,
"islnk": false,
"isreg": true,
"issock": false,
"isuid": false,
"mode": "0644",
"mtime": 1554394659.885133,
"nlink": 1,
"path": "/tmp/etc/httpd/httpd.conf",
"pw_name": "lars",
"rgrp": true,
"roth": true,
"rusr": true,
"size": 11753,
"uid": 21937,
"wgrp": false,
"woth": false,
"wusr": true,
"xgrp": false,
"xoth": false,
"xusr": false
}
],
"matched": 1,
"msg": ""
}
}
In other words, filestoser is a dictionary. The files key contains a list of files that were matched by the files task. You could rewrite your lineinfile task like this, if you want to operate on the first file found:
- lineinfile:
path: '{{ filestoser.files.0.path }}'
state: present
regexp: '^ServerRoot'
line: 'ServerRoot_new'
