kraken EON import tariff lookup failing #3763
Description
Activity
I've been doing a little research, and it seems like the Kraken portal for EON doesn't have some of the older tariffs
Using the EON Kraken product page (https://api.eonnext-kraken.energy/v1/products/), the NEXT_SMART_SAVER_FIXED_12M_V8 is NOT present, but NEXT_SMART_SAVER_FIXED_12M_V16 is. V16 is the only smart saver variant.
So, it seems like it is not an issue with Predbat; EON isn't fully populating their products.
Update for v8.36.3 - with the #3776 fix.
I was hoping this might fix the tariff rate retrieval issue I had been seeing. However it is still failing to get the rates for my EON tariff.

I can confirm this is still occurring in Predbat v8.37.4.
System background:Previously configured with split import/export Kraken accounts
Export account has since been fully removed
export_enable: false explicitly set
Predbat fully restarted after all config changesCurrent behaviour (even with import‑only Kraken):
Warn: Kraken: Auth not available for find-tariffs
Warn: KrakenAPI: run() returned FalseThis does not appear to be related to credentials or YAML formatting. It also persists after disabling export, which suggests that systems which have ever run in split‑account mode may still enter a state where no valid auth token is available at find‑tariffs time, even when operating import‑only later.
For context, this looks like the same failure mode previously discussed in #3681 and #3733, but still present in the latest release.

Describe the bug
Retrieval of my EDF import tariff rates and standing charge is failing but the export tariff rate is working. The import and export tariff names are both been identified correctly.
History of previous issues with getting Kraken to work with EDF.
#3733 #3681
Below is the URL it uses to try and retrieve the import rates which returns
{"detail":"Not found."}when you put it in a browser. I had done some research on this and reported it in my first issue post on #3733 .https://api.eonnext-kraken.energy/v1/products/NEXT_SMART_SAVER_FIXED_12M_V8/electricity-tariffs/E-TOU-NEXT_SMART_SAVER_FIXED_12M_V8-M/standard-unit-rates/
Expected behaviour
The import tariff rates and standing charge to be retrieved correctly.
Predbat version
8.36.1
