While I was reviewing the course's material in Extracting Data Types (page 181) it shows how to convert a token directly in the tokenizer ..
The problem is that date is not a valid data type
From the doc:
In fact when I tried to use date as a convert_datatype I get the following error when starting the beat
Exiting: Failed to start crawler: starting input failed: Error while initializing input: invalid data type accessing 'filebeat.inputs.0.processors.0.dissect.tokenizer' (source:'filebeat.yml')
Thank you very much
