in the data visualizer of the Machine learning, we used to have a feature to upload a csv.
there is blog about that https://www.elastic.co/blog/importing-csv-and-log-data-into-elasticsearch-with-file-data-visualizer
It worked very fine in version 6 when the csv does not have a timestamp.
I migrated from version 6.5 to version 7. and now it does not work anymore if the csv does not contain any timestamp.
The error message is:
File could not be read
[illegal_argument_exception] Could not find a timestamp in the sample provided
How can I overcome this ?
this feature was very useful indeed !
