Handshake extraction failed!

Exclamation 
Hello I have this error message when trying to convert a pcap file from a pmkid sniffer (esp32 marauder).
It has multiple eapol lines that should contain the encoded wifi password in it so I don't know why it doesn't work, thanks for your help !

Information: limited dump file format detected!
This file format is a very basic format to save captured network data.
It is recommended to use PCAP Next Generation dump file format (or pcapng for short) instead.
The PCAP Next Generation dump file format is an attempt to overcome the limitations
of the currently widely used (but very limited) libpcap (cap, pcap) format.

Information: radiotap header is missing!
Radiotap is a de facto standard for 802.11 frame injection and
