Hello Team,
We are referring your solution to send LtiDeepLinkingResponse. With this solution able to generate JSON response as

 {
          "https://purl.imsglobal.org/spec/lti/claim/message_type": "LtiDeepLinkingResponse",
          "https://purl.imsglobal.org/spec/lti/claim/version": "1.3.0",
          "iss": "1000000101",
          "aud": "https://canvas.instructure.com",
          "exp": "1674104792",
          "iat": "1674104492",
          "nonce": "gdT446jJTgc",
          "azp": "0omiNPx2v5Q",
          "https://purl.imsglobal.org/spec/lti/claim/deployment_id": "11767:105256654",
          "https://purl.imsglobal.org/spec/lti-dl/claim/content_items": [
            {
              "custom": {
                "activity_id": "0"
              },
              "text": "Module Description",
              "title": "ModuleName",
              "type": "ltiResourceLink",
              "url": "our_web_page.html"
            }
          ]
        }

 private static ContentResult Post(string name, string value, string url)
        {
            return new ContentResult
            {
                Content = "<html><head><title></title></head><body onload=\"document.contentitems.submit()\">"
                          + $"<form name=\"contentitems\" method=\"post\" action=\"{url}\">"
                          + $"<input type=\"hidden\" name=\"{name}\" value=\"{value}\" /></body></html>",
                ContentType = "text/html",
                StatusCode = StatusCodes.Status200OK
            };
        }

But when we try to send this using Post method, it is giving an error as - {"errors":{"jwt":[{"attribute":"jwt","type":"JWT format is invalid","message":"JWT format is invalid"}]}}
Could you please guide, what is missing in our implementation or anything we need to cross check?
