InfluxDB batch insert only inserts the last line I'm trying to insert some lines into a InfluxDB instance (running on Windows 7 x64) from both a .txt and a .csv file, but it's only inserting the last line on the file.

I'm currently using the Insomnia interface to send the file through Influx's HTTP API.
Example:  

I have the following content inside a data.txt file:

any,mytag=ab value=59
any,mytag=ab value=78
any,mytag=ab value=102


All lines are ending with LF only (verifying it through N++).
Then I send this file via an HTTP request to my running InfluxDB instance:

POST http://localhost:8086/write?db=mydb&amp;precision=ns


Yet, when I do a select * from "any" query, it shows that only the last line (value=102) was inserted. I've also tried inserting through text/plain content but to no success as well.

Any idea on this?

Thanks.
I've tested it out and apparently you need the timestamps on the end of each line. Thus the file should look like: 

any,mytag=ab value=59 1555003566890381500
any,mytag=ab value=78 1555003566890381500
any,mytag=ab value=102 1555003566890381500


Now I wonder if you can insert them without the timestamp.
