Cant sett hilsen eller 'Get Started' -knappen for facebook chatbot etter gang satt

Jeg prøver å redigere Velkomstmelding for min FB chatbot, kommandoene resulterer suksess, men velkomstmeldingen endres ikke.

Også Kom i gang-knapp: jeg kunne sette det lykkes for første gang, men etter en gang å slette, er ikke knappen vises selv om kommando resultater suksess hver gang.

kode for å sette hilsen melding:

curl -X POST -H Content-Type: application/json -d '{
  setting_type:greeting,
  greeting:{
    text:Timeless apparel for the masses.
  }
}' https://graph.facebook.com/v2.6/me/thread_settings?access_token=PAGE_ACCESS_TOKEN   

for å slette hilsenen Message

curl -X DELETE -H Content-Type: application/json -d '{
  setting_type:greeting
}' https://graph.facebook.com/v2.6/me/thread_settings?access_token=PAGE_ACCESS_TOKEN

for å legge Startveiledning Button

curl -X POST -H Content-Type: application/json -d '{ 
  get_started:{
    payload:GET_STARTED_PAYLOAD
  }
}' https://graph.facebook.com/v2.6/me/messenger_profile?access_token=PAGE_ACCESS_TOKEN  

for å slette Startveiledning knapp:

curl -X DELETE -H Content-Type: application/json -d '{
  fields:[
    get_started
  ]
}' https://graph.facebook.com/v2.6/me/messenger_profile?access_token=PAGE_ACCESS_TOKEN 

Jeg bruker Terminal til å kjøre disse kommandoene.
