Anyone want to test/review my PR? Here is the changed file directly: https://github.com/Revadike/epicgames-freebies-claimer/blob/766ae427192417d4105930d098a006fc795ac031/src/gamePromotions.js

I think those endpoints can be replaced with https://www.epicgames.com/graphql?operationName=getMappingByPageSlug&variables={"pageSlug":"paladins--paladins-epic-pack"}&extensions={"persistedQuery":{"version":1,"sha256Hash":"5a08e9869c983776596498e0c4052c55f9e54c79e18a303cd5eb9a46be55c7d7"}}

But here the problem is calculating the hash, which I am currently looking into.

Docker image is updated. Sorry for the delay, it was 2AM at my timezone when v1.5.5 was released lol.

This bug is not related to device auth, just wait for a fix.

Hmm I’m also sniffing the traffic, from the addon page, but I didn’t find that one. What action do you do (or visit which page) to get that one?

When visiting https://www.epicgames.com/store/en-US/p/paladins--paladins-epic-pack

Nice find. I don’t think we need to calculate the hash, try another addon:

https://www.epicgames.com/graphql?operationName=getMappingByPageSlug&variables={“pageSlug”:“horizon-chase-turbo--horizon-chase-turbo-rookie-series”}&extensions={“persistedQuery”:{“version”:1,“sha256Hash”:“5a08e9869c983776596498e0c4052c55f9e54c79e18a303cd5eb9a46be55c7d7”}}

This is for https://www.epicgames.com/store/en-US/p/horizon-chase-turbo--horizon-chase-turbo-rookie-series

I think the hash is for the query itself, so we can reuse the hash. Btw how did you find this query lol.
