Partial archive nodes on Erigon are archive nodes that only cover a specified block range, so they index everything but only for blocks after X, and/or before Y, or in the last Z blocks.
When chifra tries to detect whether tracing is enabled on a node it currently checks for traces on block 1, which might not be in the range that is archived.
@tjayrush - Do you know if there's some way to query for 'firstArchivedBlock`? In most cases this would be block 1 (or 0). In your case (with a "partial archive") it would return 19,00,000. We don't really care which block we check, just that we check the first available one. (It would be an easy fix if there was such a query on the RPC, but I doubt there is.)
@dreadedhamish - There is nothing in the erigon API to get first block.
It might be easiest to add some options to trueBlocks.toml (beginTrace & endTrace).
alternatively there is the command:
for a regular install: ./build/bin/integration print_stages --datadir= --chain=gnosis
docker after exec'ing in: integration print_stages --datadir= --chain=gnosis
That will print out information on stages and their pruning status, and then one key line:
prune distance: --prune.r.older=90000 --prune.h.before=17232999 --prune.t.before=17232999 --prune.c.before=17232999
You'd have to look out for prune.t.before= or prune.t.after= with block number, and prune.t.older= number of blocks.
@tjayrush - I don't love using an Erigon specific endpoint, although it won't be the first time. Reth probably does it differently.

@dszlachta suggested a workaround by manually editing this file: https://github.com/TrueBlocks/trueblocks-core/blob/master/src/apps/chifra/pkg/rpc/is_node.go#L41
