I used this library for basic_lti_launch and content item selection.
Tool Consumer: Canvas
Account: Test Account(Free for teacher) of canvas
The library was working good.After some days at the time of new assignment creation, it failed to launch. After debugging I found it failed to match the signature. Old assignments are working fine. But no new assignment is working which uses this new library.
My old library (which do not have the support of contentItem) is working fine.
My question is why suddenly it stops matching the signature? What is the cause behind it?
Please suggest me the possible solution.
