Import data to thingspeak


I want to import data from a .cvs with the requested format but constantly the same error comes out : "The uploaded file was not imported because it is missing timestamps."
My data is in this format:
created_at,field1,field2,field3
1600064881,50.818,0,0
Could someone help me fix it?
Thank you

I just used the template provided at the import tab on my ThingSpeak channel, it includes epoch format.The file worked fine for me. Can you download the template and use that for your data?

Using the template it works perfectly, the only thing that missing was the id.
Thank you so much
