Custom Threat Intelligence Error

Hi Elastic Community,

I have testing a new integration Custom Threat Intelligence into elastic and I found some error like below:

I have configure the column of SSL Configuration like below:

certificate:

- |

-----BEGIN PRIVATE KEY-----

MIIEvgIBADANBgkqhkiG9w0BAQEFAASCBKgwggSkAgEAAoIBAQDWbCQ6iiLAZVr5

85zKU8aI5S========================================================

-----END PRIVATE KEY-----

Do you have any suggestion or you have experience about same error?. Or there is any problem with above configuration?

Accept Love
