Cloudflare blocking occurs after updating to @urql/core v6.x

[GollyJer]

After updating @urql/core from v5.x to v6.0.1 and @urql/exchange-auth from v2.2.1 to v3.0.0, GraphQL requests are being blocked by Cloudflare instead of reaching the Hasura GraphQL server.

This feels like a header/token issue but I'm not sure where to start. Downgrading the packages and restarting the dev app causes it to go back to working as expected. I can't find any migration instructions for these packages.

Any help is greatly appreciated. Thanks.

Maybe your GraphQL server doesn't allow for GET queries https://github.com/urql-graphql/urql/blob/main/packages/core/CHANGELOG.md#600 - which is part of the HTTP spec

ok, cool. Thanks for that info. (I should have found it myself 😀)

We're running a Hasura 2.x server. They have a separate REST api, but I'm not sure if the graphql side accepts GET queries. Looking into it and will report back.

Thanks for the heads up @JoviDeCroock. After some research, Hasura v2 does not support graphql GET requests.
I added preferGetMethod: false, to our client and we got past the Cloudflare block.

But now there is a new issue with exchange-auth. 👉 #3829
