Hi,

I have an application running, which is accepting the post request to add
targets in the path /etc/prometheus/config/target.json.

Currently, I'm posting 2-3 targets using curl to the application which in
turn adds to the Prometheus path, post is happening in a time difference of
2-3 minutes.

In Prometheus UI, I could see it is adding only one target or can see only
one target in service discovery, but I have added 3 targets.

could see some errors in Prometheus:

ts=2023-12-12T10:27:15.936Z caller=file.go:343 level=error
component="discovery manager scrape" discovery=file config=ne-federation
msg="Error reading file" path=/etc/prometheus/config/targets.json
err="unexpected end of JSON input"
ts=2023-12-12T10:35:50.707Z caller=file.go:343 level=error
component="discovery manager scrape" discovery=file config=ne-federation
msg="Error reading file" path=/etc/prometheus/config/argets.json
err="unexpected end of JSON input"

I checked the JSON file using JSON validator, it's perfectly valid.

can you please help with what could be the issue?
