Research direction

Start with ApiConfig::DEFAULT_CHUNK_SIZE and the upload flow in UploadTrait.php, ApiClient.php, and BaseApiClient.php, especially the response handling around BaseApiClient.php:417. Reproduce an upload larger than 20 MB with the default chunk size, then verify that chunked uploads complete without a General Error and remain consistent with the documented behavior.

Description

I noticed, that the API returned a "General Error" when I tried to upload an image that is larger than 20 MB.
After some research I found a matching issue in the cloudinary_android-Repo: https://github.com/cloudinary/cloudinary_android/issues/148.
After reading the docs (https://cloudinary.com/documentation/upload_images#chunked_asset_upload), I set the chunk_size to a value that is larger than 20 MB (e. g. 30000000) when calling the upload-function.
That fixed my problem. However, the Chunked asset upload feature doesn't seem to work.

Issue Type (Can be multiple)

  • Behaviour - Functions aren’t working as expected (such as generate URL)
  • Documentation - Inconsistency between the docs and behaviour

Steps to reproduce

Try to upload a file larger than 20 MB (or the \Cloudinary\Configuration\ApiConfig::DEFAULT_CHUNK_SIZE respectively).
