I am new to KNIME and currently I am trying to find out how to implement a proper error handling for my data manipulation flows.
This is what I want to do:
- Read Excel File
- Data Manipulation
- Export CSV File
- if Success, then send email with success message
- if Error (e.g. Read Excel failed, because no file available), then send email with error message
I played around with Try Catch nodes but I really have no clou how to configure and use them correctly. In my mind the flow should look something like this but propably it is nonsense:
Can someone help me? How to configre the flow, that error message email is sent, if Excel Reader fails.
