Facebook OAuth issue Dreamfactory -

i getting error while trying implement facebook oauth in ionic app.

this how post request url looks like:

https://df-apiurl.com/api/v2/user/session?oauth_callback=true&service=facebook&code=**********&state=********

here error response. relevant part might be:

"message":"client error: post https://graph.facebook.com/oauth/access_token resulted in 400 bad request response:\n{"error":{"message":"error validating verification code. please make sure redirect_uri identical 1 (truncated...)\n"

but here full error message in case.

{"error":{"context":null,"message":"client error: post https://graph.facebook.com/oauth/access_token resulted in 400 bad request response:\n{"error":{"message":"error validating verification code. please make sure redirect_uri identical 1 (truncated...)\n","code":400,"trace":["0 /opt/bitnami/apps/dreamfactory/htdocs/vendor/guzzlehttp/guzzle/src/middleware.php(65):
