Hi Ashirwad,
Seems that your issue is related with the path of the certificate because is returning a null value.
Take a look at this docs:
- Teach you how to configure the certificates on the environment (https://docs.mendix.com/developerportal/deploy/certificates/)
- Configure locally (https://docs.mendix.com/howto/integration/use-a-client-certificate/)
If this answer helped you, please mark as accept :)
Best Regards,
Ricardo Pereira
