Demo grant request failing

[wilsonianb]

The demo Grant Request Incoming Payment Postman request is currently failing with:

local-database-1      | 2022-11-28 01:32:28.608 UTC [70] ERROR:  null value in column "clientKeyId" of relation "grants" violates not-null constraint

I think this is due to:

rafiki/infrastructure/local/peer-docker-compose.yml

Line 17 in 5a19201

BYPASS_SIGNATURE_VALIDATION: "true"

which bypasses clientKeyId being defined in:

• fix(auth): add clientKeyId to context #769

This could be solved with:

• Return client payment pointer in introspection response #737

@wilsonianb In the meantime, until we have decided on and rolled out #737 , I was thinking we could do something like this:

https://github.com/interledger/rafiki/pull/792/files#r1033413462

i.e. we could provide a key via the header in the meantime

@raducristianpopa I believe you will need this fix as well to test your open PR, tagging you so you can follow along

Closing as #797 makes the demo work
