Hi Sanchit,

Thank you for reaching out with your question about LTI substitution parameters.

I would suggest reaching out to our Support team with details about your specific course, the steps you followed to copy or create the assignment, and where you are launching the LTI tool from. Please also include any relevant screenshots or logs showing the empty substitution variables. This information will help our Support team investigate why the specific related variables are not being populated as expected.

Thank you,

John
