lti 1.3 tool launch not receving custom parameter from thin common cartridge resource file

[anurag_biradar]

tcc package imported to canvas course and on launch 1.3 tool that resource custom value are not receiving on launch .

for every resource file we are adding custom sku i.e

<blti:custom>
<lticm:property name="sku">X45352</lticm:property>
</blti:custom>

but this custom sku is not getting in custom claims on launch

I, also, would like to know if there is a special configuration I need to implement in order for the custom parameters from my thin common cartridge to be appended to the LTI 1.3/Advantage launch request.
