[Bug]: Error 500 on podserver public page

[johnongit]

What is your BTCPay version?

I'm running BTCPay V1.6.11.0

How did you deploy BTCPay Server?

I'm running BTCPAY Server based on docker on a VPS

What happened?

I'have an HTTP error 500 page with podserver public page.
https://btcpay.openchain.fr/plugins/podserver/podcast/testazeazezaeaze

How did you encounter this bug?

1. Create a podcast (with or without RSS feed).
2. Open public page
3. HTTP error 500 page is displayed instead of podcast public page.

Relevant log output

Are you sure this is a bug report?

• I confirm this is a bug report

I'll fix this in v0.1.1 - for now you can circumvent it by adding an episode.

On Twitter you also mentioned a problem with the import. Can you add a separate issue with the logs for that as well?

[pavlenex]

Moved to plguin repo #46

Ok thx @dennisreimann
By adding manually an episode, I can see the episode public page. https://btcpay.openchain.fr/plugins/podserver/podcast/testazeazezaeaze/test10.
