Undefined 'indexing_options' at EmbeddingBase.php

It seems like you haven't configured Fields in your Search API Index? Please go to the Fields tab and chose Indexing Options; there should be a fair amount of on-page documentation explaining what to do there. Let us know if you get stuck. Thanks

This adds a helper warning to the search index status page to indicate whether indexing options have been set.

Updated issue summary to make it clear how to reproduce (ie, 'Save', not 'Save and add fields' and never use add Fields tab)

Feels like a SAPI issue rather than an AI issue (what would the index do if it was set up without fields?) but code looks good and works so RTBC.

It appears that the issue was indeed as mentioned:

It seems like you haven't configured Fields in your Search API Index?

I needed to set up that configuration. I didn't pay enough attention, as I assumed that enabling the search recipe would automatically configure an index and a server.

This is the missing configuration.

This shows the Pinecone index after rebuilding it.

My English isn't perfect, so I couldn't find any documentation addressing this specific issue. It’s possible that I simply overlooked it – a classic case of "where did I put my glasses?" But I genuinely believe that it would be beneficial for the Drupal community if the CMS came with the Help module enabled by default. Additionally, creating a help guide there could assist users who aren't experts in coding to better navigate through the Drupal CMS.

Anyway, thank you all for your support! I'm glad to say that my problem has been resolved.

Thanks for confirming. Will merge in the branch so you see a big yellow warning instead next time (or future site builders)
