invalid write key

[esmaeilram]

i generated workspace.json from the dashboard, I added it to rudderstack and it's imported properly in rudder-stack backend pod but I still get an invalid write-key error when I send a post request to my data plane. webhook post http://dataplane-url/v1/webhook?writeKey=$writekey { "stage": { "user_transform": true, "dest_transform": true, "send_to_destination": true }, "message": { // RudderStack HTTP Payload (identify, track, etc.) } } ps

response is :

ps: My webhook post is working in rudderstack dashboard cloud but I want to host the opensource dashboard

any idea?
