Hoping to use one flow to monitor multiple columns in a single list

[bm_data]

I have a SharePoint list that is a job log. There is a person column and a date column for multiple teams.

Column examples

Sales Person

Sales due by date

Marketing Perspn

Marketing due by date

Manufacturing Person

Manufacturing due by date

ect

What I would like to do, if possible, is use the trigger "When an item is modified" then "Get changes (properties only). With that data I am trying to use a switches in a parallel fashion to monitor a few different columns to say if column "Sales" was changed send email to the user name in that column, if column "Marketing due by date" is updated email the user in column "Manufacturing" and so on.

My issue is the switch function does not allow Boolean or at least that is what my error states. I think this could also be done using a condition however I believe I will hit the limit based on my needs.

Could you use 3 parallel conditions?

Very similar to a Switch and these aren't nested so there should not be an issue with limits.

That is what I am doing. If I use "Column A has changed" as the condition and Equals "True" I get 

The execution of template action 'Engineer' failed: The result of the evaluation of 'scope' action expression '@outputs('Get_changes_for_an_item_or_a_file_(properties_only)')?['body/ColumnHasChanged/Engineer']' is not valid. It is of type 'Boolean' but is expected to be a value of type 'String, Integer'.

If I use "true" I then get this error upon saving the flow: 

Request to XRM API failed with error: 'Message: Flow client error returned with status code "BadRequest" and details "{"error":{"code":"InvalidOpenApiFlow","message":"Flow save failed with code 'InvalidTemplate' and message 'The template validation failed: 'The template action 'Engineer' at line '1' and column '2196' is not valid: the value 'True' specified for 'case' property in switch case 'Case' is not allowed. Only values of types string, number or a '@parameters()' expression that evaluates to a number or a string is allowed.'.'."}}". Code: 0x80060467 InnerError: '.

Can you show a screenshot of your flow in edit mode and then show a screenshot of your flow with the error?

I'm not able to tell from the text alone.

Boolean is always tricky in power automate, sometimes it is "true" "false" sometimes it is "Yes" "No" and sometimes it is 1 or 0. You have to test what works. 

If I can see your screenshot it will help,

I can only show the error in edit mode when I use the equals "true" when I use equals "True" I am able to run the flow but fails as seen in the attached. If I used "Yes" "No" "1" "2"  or anything else I again am able to save but get that same error.

You can't use a Boolean with a Switch. You will need to convert the boolean to a string.

Wrap your {HasColumnChanged} with the string() function and then for the Case put True.

@wskinnermctc I tested your suggestion and that was able to get me past that step, thank you for the advice!
