chainHead_v1_call always yields operationInaccessible events for DryRunApi_dry_run_call

[josepot]

The DryRunApi_dry_run_call runtime-API always yields an operationInaccessible event, making it unusable with smoldot.

This runtime-api is very useful for calculating the XCM delivery fees and for many other use-cases.

This issue is preventing the following PR from being merged.

I have created the following repo to reproduce this issue, using this code (the exact same code works with a WebSocket provider).

The logs that I captured after running that code:

• Wire logs
• Smoldot logs

I'm more than willing to test this problem with a custom build of smoldot and/or to provide any other assistance to get to the bottom of this issue.

Here's a branch that you can please use: https://github.com/tomaka/smoldot/tree/debug-2035
It will generate the logs that interest me.

[josepot]

The updated logs that I obtained from the build of the custom branch:

• Smoldot logs
• Wire logs

Thank you so much to both of you for your help with this problem, and for solving it so fast!

[josepot]

Unfortunately, the issue persists with the latest version of smoldot (2.0.32). So, I think that this issue was prematurely closed.

The logs:

• smoldot-logs.txt
• wire-logs.txt

[tomaka]

There's more than one bug, then. I've updated my branch above.

[josepot]

New logs with the custom build:

• smoldot-logs.txt
• wire-logs.txt

[tomaka]

Before I release a version, could you try again with #2039 ? (or with the main branch, as I'm going to merge that PR no matter what)

I've also already merged #2039 onto the branch above in case it fails again.

Still not working, the logs (with the custom build):

• smoldot-logs.txt
• wire-logs.txt

[tomaka]

Opened #2041 and updated the branch above.

Opened #2041 and updated the branch above.

Third time's the charm!!! It works! Thanks @tomaka !

[0xKheops]

Thanks!

[tomaka]

I'm afk for a few hours now, but I'll publish a version later today.

[josepot]

Unfortunately, we just noticed that this issue still exists with kusama 😞

• smoldot-logs.txt
• wire-logs.txt

EDIT:

For some reason the build from the branch debug-2035 is not producing logs against kusama 🤔

[tomaka]

The debug-2035 branch is additional logs about a specific bug. I need the generic logs again.

here you go, generic logs of the same code as before but running it against the Kusama relay-chain and using the latest main on smoldot:

• smoldot-logs.txt
• wire-logs.txt

[tomaka]

This new problem is the same as #1985, so I'm going to close this one again.
