The work around is to explicitly supply a list of strings for the `paths` arguments.

However, we could (and should) improve this error message, to clarify what's going on here. Actually, we should probably raise an error message is `paths` is a string starting with `http://` or `https://` before trying glob.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,317114207

you'll see we are using `glob` to expand the path names. This is not likely to work for URLs. I'm not 100% sure if it is even possible to do a path expansion on OpenDAP datasets. 

If you can do the expansion yourself, that would be the easiest workaround. ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,317114207
