google.api_core.exceptions.InternalServerError: 500 An internal error has occurred. Please retry or report in https://developers.generativeai.google/guide/troubleshooting

### Description of the bug:

**I have a dataset with 148 rows and 12 columns and want to generate text for each cell with the Gemini API. Now the error that occurs is 'google.api_core.exceptions.InternalServerError: 500 An internal error has occurred. Please retry or report in https://developers.generativeai.google/guide/troubleshooting' I activated my Account under the Google Cloud. Sometimes it generates the first few columns before the error occurs and sometimes it directly returns the error. Did anyone solve this for good?**
