NullReferenceException on not passing claim 'https://purl.imsglobal.org/spec/lti/claim/tool_platform '

[parulrawat-compro]

According to IMS LTI 1.3 Specification claim "https://purl.imsglobal.org/spec/lti/claim/tool_platform" is not a mandatory claim.

However the Tool crashes and throws an error on not passing the same.

Did you ever find a fix for this @parulrawat-compro ?

I'm having the exact same error.
