Generic error when performing first upsert into a new index

Hi everyone,
I using Flowise deployed into a Render environment and it was working with Pinecone for days. But today I deleted my index to start a new one from zero and it stopped working. Then I deleted my project and created a new one and then a I saw that it was created on a new free environment since I am not a paid user, then I thought that this could be the problem, but even with a new project deployed on free environment, its not working and I am receiving the following error:

ErrorWithoutStackTrace: PineconeClient: Error calling upsert: Error Without StackTrace: PineconeClient: Error calling upsert Raw: FetchError: The request failed and the interceptors did not return an alternative response

Solved when deleting chatbot on Flowise AI and creating a new one.
