i’m running into the following error when running tests with pocket-ic on the most recent versions;
After upgrading from;
dfx version: 0.26.0
ic-cdk: 0.17.1
pocket-ic: 0.7.0
pocket-ic-server: 0.8.0
to;
dfx version: 0.26.0
ic-cdk: 0.18.0
pocket-ic: 0.8.0
pocket-ic-server: 0.9.0 (also tried 0.8.0)
> also had to include the "ic-management-canister-types" crate
im getting the following error;
