AdCampaignDeliveryEstimate TypeError problems

[adam-szczombrowski]

Hi, maybe I'm not getting something here but when I get delivery estimate for adset I cannot read the responses data, almost all methods beside to_yaml return

TypeError: no implicit conversion of Hash into String. It seems to me like there is a bug in the gem.

@alanho could you please look into it? I'm unable to get any attribute values on delivery_estimate object. It always returns Undefined method estimate_dau and similar to that.

hi @adam-szczombrowski , sorry for the delayed response. do you have any sample code that could reproduce the problem that i could look at?

[adam-szczombrowski]

client = FacebookAds::AdAccount.get(@account_id, {access_token: @access_token, app_secret: FacebookAds.config.app_secret })

delivery_estimate = client.adsets.first.delivery_estimate

and now whenever trying to send methods to delivery_estimate object it raises TypeError (the only method I found working is to_yaml)

@alanho here is the output from rails console:

[1] pry(main)> client = Facebook::GetClient.new(User.first).call
  User Load (2.2ms)  SELECT  "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT $1  [["LIMIT", 1]]
