Other day while working on error handling scenario in my Cloud Flow, my Flow Checker given me following error.

Correct to include a valid reference to ‘Data Operation Divide‘ for the unput parameters(s) of action ‘Set_Error_Message‘.

Error from Flow checker

Lets see the reason and fix for this error.

Reason:

• In my flow, I am capturing the error message of my Compose action by name Data Operation Divide in my Set Variable action by name Set Error Message.
• My Data Operation Divide compose action does a simple division operation of ‘numA’ and ‘numB’ values using div function.

• My Set Error Message action configured to run only when Data Operation Divide compose action fails.

• Set Error Message action ‘Value’ configured with actions expression to read the Data Operation Divide action’s error.
  • The expressions used is actions(‘Data Operation Divide‘)?[‘error’]?[‘message’]

• Everything does looks fine right?. Then where is the error?.
• The answer is actions expression does not accept spaces in the action name. In my case, action name is ‘Data Operation Divide‘ which has got spaces.
• Hence the ‘Flow Checker’ showing Correct to include a valid reference to ‘Data Operation Divide‘ for the unput parameters(s) of action ‘Set_Error_Message‘ error.

Fix:

• In the actions expression of Set Error Message action ‘Value’ parameter, replace spaces with underscore(_).
  • Formula looks as below actions(‘Data_Operation_Divide‘)?[‘error’]?[‘message’]
• Notice the ‘Flow Checker’ and error is gone.

• Run the flow with ‘numA’ as 10 and ‘numB’ as 0.

• And the ‘Set_Error_Message‘ error action show the error message.

• So the bottom line, actions expression does not accept spaces in the action name.
