-----------------------------------------

             Summary: "Error: blob is undefined" when creating new SessionRecording from Blob
                 Key: GUACAMOLE-1793
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1793
             Project: Guacamole
          Issue Type: Bug
          Components: guacamole-common-js
    Affects Versions: 1.5.1
            Reporter: Leonard Wagner


When creating a {{Guacamole.SessionRecording}} instance by supplying a blob an error is thrown.

To reproduce this, run the following test:
{code:javascript}
describe("Guacamole.SessionRecording", function EventSpec() {
    it("should create new SessionRecording instance from Blob", async function () {
        const url = 'https://raw.githubusercontent.com/apache/' +
            'guacamole-client/master/doc/guacamole-playback-example/src/main/webapp/recording.guac';
        const response = await fetch(url);
        const blob = await response.blob();
        const recording = new Guacamole.SessionRecording(blob);
        expect(recording).not.toBeNull();
    });
});
{code}
Expected result: The test passes without an error.
Actual behavior: An error is thrown when calling the constructor function.
{code:java}
TypeError: blob is undefined in src/main/webapp/modules/SessionRecording.js (line 280)
