bookmark causes error

[Harshone1]

Hello,

{{BrightspaceDomain}}/d2l/api/lp/{{lpversion}}/enrollments/users/{{userid}}/orgUnits/?bookmark={{bookmark}}

When running this in Chrome I get a 403 error which would make you think it's a permission issue but I'm able to paste into the address bar and it works so that is not the cause.

When running this in Firefox I receive an error:
The resource from “https://mydomain/d2l/api/lp/1.30/enrollments/users/67442/orgUnits/?bookmark=89534&x_t=1614878024&x_a=o2t5r_5UTC2FLx3EJQPcsA&x_c=jOy_ALXQ0jTTjJYJ_tH6DnAUx4RUEjWAxJH1pbklGZ0&x_b=GKD5-w7TjnM588PmepiXzG&x_d=wgJstvQEDhK68SE8Icrw-Yv-MfaOy_tMzBNipBIeHRY&callback=_jqjsp&_1614878024255=” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff). {Learn More]

Please let me know what I might be doing wrong?

Thank you for this great resource!
