Studio Dev 61997 hosted execution stuck in invalid DB transaction rollback state #1790
Description
Summary
Studio Dev RPC basic reads are healthy, but hosted GenLayer execution and fee simulation fail consistently with a PostgreSQL/SQLAlchemy transaction rollback error.
Environment
- Network: Studio Dev
- Chain ID: 61997 (RPC returned 0xf22d)
- RPC: https://studio-dev.genlayer.com/api
- GenLayer CLI: 0.40.0-rc.3
- genlayer-js: 2.0.0-rc.1
- Client: viem 2.56.5
- Existing contract under read-only investigation: 0x33735bbaa9595FBB1b8a9fFCC3A91103911baEdC
- No transaction was signed or submitted during this report.
Fresh read-only results
These calls returned HTTP 200 / JSON-RPC success:
- eth_chainId -> 0xf22d
- eth_blockNumber -> 0x6acea28e (at 2026-10-13T21:32Z)
- eth_getBalance(0x33735bbaa9595FBB1b8a9fFCC3A91103911baEdC, latest) -> 0x2
Failing methods
- gen_call through CLI, reading get_challenge("reprobond-steward-recovery-20261012-a")
- Installed SDK estimateTransactionFeesForWrite for a concrete payable write:
- to: 0x33735bbaa9595FBB1b8a9fFCC3A91103911baEdC
- method: fund_challenge
- args: ["reprobond-steward-recovery-20261012-a"]
- user value: 2 wei
- transaction hash variant: latest-nonfinal
Both return JSON-RPC error -32603:
Can't reconnect until invalid transaction is rolled back. Please rollback() fully before proceeding (Background on this error at: https://sqlalche.me/e/20/8s2b)
The SDK surfaces InternalRpcError, shortMessage: "An internal error was received.", with the same text in details and cause.
The error reproduced in a fresh CLI process and fresh SDK process, including two bounded retries 10 seconds apart. Raw RPC reads continued to work. No client-side reset, database manipulation, signing, or transaction submission was attempted.
Please inspect and roll back/clear the server-side invalid database transaction for the Studio Dev execution/fee-estimation path, and advise when gen_call and sim_estimateTransactionFees are healthy again.

Comparison update (2026-10-14)
A fresh read-only comparison confirms the failure is hosted Studio Dev execution-path wide, not ReproBond-specific.
Read-only gen_call matrix
Using installed CLI 0.40.0-rc.3 against https://studio-dev.genlayer.com/api:
All four independent fresh CLI calls returned:
Can't reconnect until invalid transaction is rolled back. Please rollback() fully before proceeding (Background on this error at: https://sqlalche.me/e/20/8s2b)
Fee-estimation comparison
Conclusion: raw reads and generic fee policy are healthy, but hosted gen_call and concrete simulation-derived fee estimation are unavailable globally on Studio Dev. No transaction was signed or submitted. Please inspect/rollback the server-side transaction state for the execution path.

Studio Next comparison (2026-10-14)
Read-only comparison was performed against both:
Both DNS names resolve to the same Cloudflare IPv4 addresses observed from WSL: 104.21.53.84 and 172.67.210.182. Both HTTPS endpoints respond as JSON-RPC POST services.
Both return chain ID 0xf22d (61997). At the comparison time, latest block numbers were 0x6acf5b38 and 0x6acf5b3c, later 0x6acf5b53 and 0x6acf5b54. At common block 0x6acf5b53, both returned the same zero block hash and zero parent/state/transaction roots; the RPC's block object does not provide a usable cryptographic hash in this environment, so that field cannot independently prove state identity. More useful state identity checks matched exactly:
Using the installed genlayer-js 2.0.0-rc.1 with the verified existing RPC override pattern
{ ...studioDevnet, id: 61997, name: "GenLayer Studio Dev", rpcUrls: { default: { http: [RPC_URL] } } }, the identical calls produced identical failures:Exact details on both endpoints: Can't reconnect until invalid transaction is rolled back. Please rollback() fully before proceeding (https://sqlalche.me/e/20/8s2b).
Conclusion: Studio Next is not an alternate execution path for this incident. It exposes the same hosted backend/service behavior as Studio Dev for consensus calls and concrete fee simulation. No transaction was signed or submitted.
fix(validators): roll back the registry session on failure (#1795)
