I am trying to upgrade my parachain node from v1.12.0 to v1.13.0 using psvm but it does not compile successfully due to some mismatch conversion error of libp2p. I believe this PR must cause that issue but not sure how to fix it. https://github.com/paritytech/polkadot-sdk/pull/4198

I encountered a similar problem when updating from 1.6 to 1.13. After analyzing the cargo.lock file and using the cargo tree command to help me, I isolated the problematic dependencies and resolved the issue by forcing specific versions instead of using the latest version using the --precise flag(^1) provided by cargo. E.g.

cargo update sc-network-types --precise 0.12.0

  • Thank you for fast response, after running the command, I ended up getting the another error: the trait From<RpcModule<_>> is implemented for Methods Is this something you got as well? (Updated the post with attachment)

    You probably have to align few other dependencies: - cargo update polkadot-node-core-pvf-common --precise 14.0.0 - cargo update mmr-rpc --precise 35.0.0 - cargo update sc-rpc-server --precise 16.0.1 - cargo update sc-network-types --precise 0.12.0

  • Hi Leonardo, another issue I got is "Use of undeclared crate or module alloc " which I already added more information above. Do you know how can I solve that error?

    I would suggest using Zepter (github.com/ggwpez/zepter) to verify that all the features are propagated correctly.
