Platform integration tests failing on recent branches

[michalrus]

Context

Probably after the update of cardano-node in the Blockfrost API on 2026-02-19T02:55:30,167769000+00:00, the reference error format for transaction submission failed.

Look here:

Deploying cardano-node version v10.6.2 to dev hosts

Plan

• @michalrus to update testgen-hs dependencies to 10.6.2 (see chore: update cardano-node to 10.6.2 testgen-hs#4)
• @ginnun to fix testgen-hs build in Encoder.hs for 10.6.2
• @michalrus to release testgen-hs 10.6.2.0 (see testgen-hs/releases/tag/10.6.2.0)
• [… the actual work …]
• unignore test_route_submit_error (see chore: temporarily ignore test_route_submit_error (submission errors changed) #460)

@ginnun WDYT? Should we update the node (and ledger) in testgen-hs, and then tweak the hardano crate in Pallas to match it? Is this the underlying issue?

[michalrus]

Temporary fix in:

• chore: temporarily ignore test_route_submit_error (submission errors changed) #460

[michalrus]

@ginnun hi! I've just created:

• chore: update cardano-node to 10.6.2 testgen-hs#4

All the 10.6.2 dependencies compile correctly, but there's a compilation error in the new Encoder.hs file (see details in the description of that PR).

Can you fix the compilation error there, and then I'll release it, so that you can work on the Rust code.

[michalrus]

testgen-hs based on cardano-node 10.6.2 has just been pre-released:

• https://github.com/input-output-hk/testgen-hs/releases/tag/10.6.2.0

So @ginnun can continue work on hardano from Pallas. Good luck! 🤞

[michalrus]

We also have a new devshell there with incremental compilation and LSP, in case you need it for this:

• feat: add a devshell for running incremental cabal build testgen-hs, editor LSP etc. testgen-hs#5

[michalrus]

Wait, this is moved to In Review, but there's no PR? 👀 I'll move it back. Or am I confused?

@michalrus I thihk this issue doesn't need to get it's own dedicated PR, since the fix was indirect. (cardano node version update in the CI)
