Everest crashes when sending an OCPP201 InstallCertificate call from OCPP server with invalid data

[BasharShehab]

Describe the bug

When running latest build of Everest-core (commit fb24707) and an OCPP server using OCPP 2.0.1, Everest crashes when receiving an InstallCertificate call with an invalid certificate_type value. In this case, an empty string:

EVerest Domain

OCPP2.0.1, Simulation

Affected EVerest Module

The bug seems to come from the module OCPP201

To Reproduce

1. Run everest
2. Run an OCPP 2.0.1 server with the standard implementation of call/call_result for InstallCertificate
3. Send an InstallCertificate call with empty string for certificate_type
4. Observe Everest logs

Anything else?

This is my first issue and I'm a newbie with everest, so I'm sorry if this isn't formatted correctly. Please let me know of any problem that needs fixing in this issue or in general, as well as any missing information that's needed.
