I have been trying to get a test case working to use the Unzip action, but all efforts fail with a -7 status ( The 'File data' input parameter did not represent a valid .zip file.).
The flow is set up very simple:
- Upload file to Azure Blob storage (Task with a file upload);
- Use “Read file” action to get the binary data for the next step;
- Use “Unzip file”
The last step has the original filename “test.zip”, the binary data and a chosen target folder “unzipped_files”. The filename is confirmed to still be the same name at the upload location.



I have even tried setting all “Encoding” options at the “Read file” action in case that was necessary, but nothing seems to change the result.
The zip file contains is just 3 .jpg images and manually downloading the file from the storage location has given a working file that I can unpack without problem.
Any idea what could be wrong or missing?
