Cryptographic Error - The specified RSA parameters are not valid

[Wazzo79]

Thank you for undertaking to solve this issue. When I run my app I get the following:

System.Security.Cryptography.CryptographicException: 'The specified RSA parameters are not valid. Exponent and Modulus are required. If D is present, it must have the same length as Modulus. If D is present, P, Q, DP, DQ, and InverseQ are required and must have half the length of Modulus, rounded up, otherwise they must be omitted.'

Do you have any idea how to resolve this?

This error is being thrown at the UseIdentityServer() method.

This library doesn't call "UseIdentityServer"... can you provide a full stack trace?
