MMA 12.2 runs just fine on the same computer using the same Notebook.

You are right, but this isn't a project, it's only a test to find ways to import something into the cloud ensuring the data is always actual. I find this is interesting for everyone who tries something like this. Regardless of the kind of data imported. I have only used this example to make it somewhat interesting :-)

A very smart solution. But the problem is, there is no way to detect changes at the laws. The original File from the Bundesministerium may change at every time. But because we are using a pre-formatted file, the answer to a query probably did not reflect the actual state. Because of this I have collected all the import functions into the query itself to ensure the right file is used. And there are several hundred other law files with the same structure. It is nearly impossible to put all of them to the cloud.

@Stefan have you tried my original cloud example? It generates a url and this can be used to query a law by number (But it didn't work) I have not tried it step by step within the cloud (because most of the day I was not able to reach the cloud desktop). I have only tried to create a url with the code above.

@Stefan I have modified my example, stripped down the code until it only contains the first Import. But fnames gives an error (didn't remember if it was False or Failed). Is it possible Import didn't support all file types? You may use my example, it runs quite well locally within Mathematica, but the cloud version did not. Importing a zipped file, extracting data from the file while doing the Import is a much more difficult functionality than importing a jpg.

Problem found (but not solved): Import[url, "FileNames"]; did not work, looks like Import is not supported by the Cloud. There is support to upload data to the cloud, so for me there is no reason why a cloud app is not able to download data from another url.

Additionally I have encapsulated everything with Module to make the variables used local. But the result ist simply the same...
