‘Failed during http send request’ error – Triggering Power automate from Canvas App

February 9, 2020 Leave a comment

While configuring Canvas app for my previous article ,I encountered following error while selecting ‘Power Automate’ from Canvas app.

Flow_Json_23

Reason:

  • In my ‘Power Automate’, I was reading collection received from Canvas app to ‘Array’ type variable.

Flow_Json_24

  • There seems to be issue with ‘Array’ datatype when triggering ‘Power Automate’ flow Canvas App.

Fix:

  • In the Power Automate, changed the Type from ‘Array’ to ‘String’ and used ‘Parse JSON’ action to convert String to json collection.

Flow_Json_25

  • In Canvas App, used JSON() function to convert the Collection to json string.

Flow_Json_30
