There is no explicit mention of a widespread or current known issue with DatasetUploadError: Internal Server Error when using px.Client.upload_dataset() on Arize cloud in the provided data sources. However, issues with dataset upload can occur due to invalid data (e.g., NaN values in your DataFrame), large dataset size causing timeouts, or server-side problems. For example, NaN values are not valid JSON and will cause upload/view errors, and large uploads may trigger timeouts even if the data appears in the UI <https://github.com/Arize-ai/phoenix/issues/7965|[source 1]> <https://github.com/Arize-ai/phoenix/issues/8482|[source 2]>.
To troubleshoot, ensure your data contains only valid JSON values (replace NaN with null), try uploading smaller batches, and check for any server/client version mismatches. If the error persists, it may be a transient server issue or a bug not yet documented. Would you like more detail on debugging steps or error handling?
