Flow using switch fails if the condition expect is not there

Posted on by lupompei Microsoft Employee

Hello,

I have a flow using switch that matches 3 entries. If there is a fourth entry and is not specified the flow failed. Ive tried to create a control (if) to tell the flow do nothing in this case, but this do not solve the problem.

The flow get all entries and check first key with control if. passing the first control goes to switch to test the entries. If matches entry 1, 2 or 3 the flow continue with no problems. Anything different fails on this step

For some reason I cant add picture here so I only can describe the flow if needed.

Really appreciate help here

Can you use this feature and add Terminate Step once the previous step fails

Switches have a default case that should pick up any cases that aren't specified. The one exception to this is if the value being evaluated is null. That causes an issue. The fix for that is to add the value being evaluated by the switch inside a Coalesce() function that will supply a default value if the none exists. In the screenshot below it uses the string "null" if a null value is found. That will go to the default case if a specific case for "null" isn't added.

You don't need to use a compose. That was just an easy way to get a null entry that I could change in a demo. You can use Coalesce() around whatever string you are using for input to the switch.
