Unable to fetch existing file. Error: "the remote file does not exist, not transferring, ignored" - file

Question

I want ansible to read a csv file in test server (10.15.170.22), but keep getting this error : "the remote file does not exist, not transferring, ignored".
This is how I structured my playbooks:
- name: Find files in sub-folders
hosts: testserverhost
tasks:
- name: Search for files in folder
win_find:
paths: C:\folder\data\
register: file
- name: set_fact
set_fact:
filename: "{{ file | json_query('files[0].filename') }}"
Since there seems to be no way for ansible to directly read the file in test server 10.15.170.22, I had to include a fetch file task before the read_csv task.
- name: Fetching file and reading data
hosts: localhost
tasks:
- name: Set fact
set_fact:
filename: "{{ hostvars['10.15.170.22']['filename'] }}"
- name: Fetch file from test server to ansible controller server
fetch:
src: C:\folder\data\{{ filename }}
dest: /var/lib/awx/projects/ansibleproject/testproject/
flat: yes
- name: Read file
read_csv:
path: /var/lib/awx/projects/ansibleproject/testproject/{{ filename }}
key: FirstName
fieldnames: FirstName,LastName
delimiter: ','
register: userdata
Output of playbooks:

I tried switching testserverhost to localhost, and also tried C:\folder\data\testdata.csv and C:/folder/data/testdata.csv for src, but I still get errors. I don't understand where did it go wrong.
