Description
Subject of the issue
I am working on a self-contained script through which one can set up a completely new Algorand network with a newly provisioned node hosted on fly.io.
In my code, I have very simple unit tests which show that I can connect to the node, but whenever I want to perform a transaction from one address to another, I get the error "TransactionPool.ingest: no pending block evaluator".
Your environment
A Dockerfile based on algorand/algod:latest
Steps to reproduce
Make sure that you have python3 and the fly CLI installed and you're logged in to your fly.io account. Then:
git clone https://github.com/hermesloom/algorand-node-flycd algorand-node-fly./setup.sh 100 EUR- Answer

Expected behaviour
The unit tests in the script local/test.py in the aforementioned repository should be executed successfully.
Actual behaviour
Unit tests test_04_transfer_funds and test_05_multiple_accounts fail with the following errors:
Using app name: algorand-node
Getting IP address for algorand-node...
Using Fly.io app IP address: <redacted>

More specifically, in my server logs I see that the error happens here in algod_client.send_transaction, but it just says HTTP Error 400: Bad Request:
