About Power DevBox Exceptions
Recording the reason for a flow failure is very difficult, this is where Power DevBox Exception comes in. It creates a bespoke expression for every flow that returns the reason for why a flow failed.
Instructions
-Goto your flow
-Click save/publish (the exception expression is generated from last full version, not draft)
-Click the Power DevBox Exception Extension icon
-Open the action with the input for the message
-Click paste
Ctrl +e will add expression to return url for flow run -
@{concat('https://make.powerautomate.com/manage/environments/', workflow()?['tags']?['environmentName'], '/flows/', workflow()?['name'], '/runs/', workflow()?['run']['name'])}
Note - expression with skip any scope/container with the word 'exception' in it, this is to stop actions used in exception handling that maybe below the message in the flow (stopping it erroring).
Some actions will not pass errors to containers, all API actions can be added by switching to New Mode by pressing Ctrl+m. To stop self referencing any action using the exception expression must have 'exception' in the name.
Update 1.1.1 changed to using Dataverse apis, so non-solution aware flows will now not work
