Research direction

Start in the TX Builder import-and-submit flow, reproduce with the linked 200-transaction JSON case and the reported 100-transaction comparison, then trace the request that returns HTTP 500 after the signature is provided. Done means the batch-size behavior is explicit and the failure reports a useful, verified result instead of a generic internal-server error.

Written by the indexing model from the issue text.

Description

When trying to import this json file with 200 txs into the tx builder, initially everything seems to work as expected:
image

Simulation succeeds:
image

image

I can provide a signature for creating the batch:
image

But after providing the signature, it fails with 500: internal server error:
image

With 100 such nested txs, it reliably succeeds.
There seems to be a hidden limit hit somewhere between 100 and 200 such transactions.
