Hi, I'm facing this issue when trying to authencate with LTI launch.

Here is my JWT: https://jwt.io/#token=eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6IjZkOTYxMGM4NWZmZDIzYzY3ZDE4MWE5M2Q3ZmY5MWVkIn0.eyJpc3MiOiIzZTBjOTZjNS0yZTM4LTRlZTAtYjkyNC0wOTg1YWIwZWExYjUiLCJhdWQiOiJodHRwczovL2FwaS5icmlnaHRzcGFjZS5jb20vb2F1dGgyL3Rva2VuIiwianRpIjoiNGNhM2IxMWNkODQzN2ZiNWM4ZTdiZTc1N2MwNmI0NDIiLCJpYXQiOjE3MTM1NjQyOTEsInN1YiI6IjNlMGM5NmM1LTJlMzgtNGVlMC1iOTI0LTA5ODVhYjBlYTFiNSIsIm5iZiI6MTcxMzU2NDI5MSwiZXhwIjoxNzEzODAwMzU5fQ.2Gg1uVfnGj8sAdi4w_pbV-mqQlQmn2m7Kwq1D8M9yS7i9NePnJl0TiBjotzCsKPMPMYAHu63mDi-9jS2XvnQzcLju_E8lXrBQVpjFYO3DOlz1XY71nxShH7lGXGQMrwbIIiB_3v4k0UrmMWDVQZfPFzji2j0Vh16iWeUqLvZ5hccE1jX4iRbGCGAlGWTPHRU1DjgHhBzvRQpAMP5XdcPyQN0TvL_AE5hk_EFOFHV4E8N5QfYONvGD1WsjCcdZ89yYA5yALeW0OaPdDktgzB4ta0yWmi4ETXtpvIPzGzEf5qXzDrfyWIvV5MFn9yvqYDYN9YgNOTbQZptl8MgMbRfuw

The error thrown:
{"error": "invalid_grant", "error_description": "Error validating assertion: Unknown validation exception"}

Do I need to add any config?
