Error [InsufficientQuotaError]: 429

When i upload a Document, the document status is set to failed because the catch block is caught with the following error:

Error [InsufficientQuotaError]: 429 You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.

I am on the free plan of openai and if i visit the billing site i have 0$ credits which is true. But the free plan should work right?
Is there anyone who had this issue and knows a solution for this?

I finally got it. If you encounter this issue, check your openai account and your billing. My Account was so old, that my free 18$ were expired. So i had to charge my account with 5 or 10$ and then generated a new API Key. It worked then!
