Errors per actions #427

Closed manuelstein closed 3 years ago

manuelstein commented 3 years ago

What happened: Using an array of actions, e.g. [functionA, functionB] can have overlapping errors, e.g. [CustomerNotFoundError]. Currently, I can only define a single error handling, but can't distinguish with which function it has occured.

Anything else we need to know?: It can be resolved with more comprehensive actions (with retry, error handling, etc. per action). Or if state nesting were to be reintroduced, each action could get its own operation state, so a list of actions (e.g. branches in foreach, switch, etc.) would become their own state chart.

Environment:
