On a rails 5.2, I save a canvas as blob and send it on azur storage via Active storage.

On my machine, with development environnement, png is created perfectly and perfectly send to the azur blob and I get it attach to the model.

But on the Test machine ( with test environnement) I get a ActiveStorage::IntegrityError when I attach the blob to the image.

the javascript that send the png

 var project_id = 2;
 var csrf_token = $("meta[name=csrf-token]").attr("content");
 var project_metadata = new FormData();
 project_metadata.append("utf8","✓");
 project_metadata.append("authenticity_token",csrf_token);
 project_metadata.append("projet_id",project_id.toString());
 project_metadata.append("commit","Create Projet");
 var file_name = "rdc.png";
 var upload_file_field = that.drawing.getElement().toBlob(function(blob) 
 var file = new File([blob], file_name, type: "image/png", lastModified: Date.now());
 var url = "/projects/"+project_id.toString()+"/store_plan"
 project_metadata.append("images",file,file_name); 
 $.ajax(
 type: "POST",
 url: url,
 data: project_metadata,
 processData: false,
 contentType: false, 
 success: function()
 console.log("images save");
 
 );
 )

The controller

def store_plan
 @project.images.attach(io: params["images"].to_io, filename: params["images"].original_filename)
end

The storage.yml

azure_dev:
 service: AzureStorage
 storage_account_name: "XXXXX"
 storage_access_key: "..."
 container: projectsdevelopment

test:
 service: AzureStorage
 storage_account_name: "XXXXX"
 storage_access_key: "..."
 container: projectstest

My dev machine is a mac book pro, my test machine is an Ubuntu.

Well don't understand why I get an ActiveStorage::IntegrityError on test and everything is ok on development?

Thanks for your help.
