I'm trying to get data for the Small Exchange SM75 instrument, and am using the string "75SME-FUT-20200821-75SME-SMFE" to try, but that could easily be incorrect somehow. The expiration date is correct, and I've tried another expiration date for an earlier contract that is also giving the same problem. The SM75 instrument is called "75SME" on interactive brokers, which is why I am using that.

When trying to get assetHistory(...) with the above name I get an error:

Download 75SME-FUT-20200717-75SME-SMFE..
Error 058: Can't parse history.json invalid response

And the history.json in question:

Found. Redirecting to /lookup?s=75SME-FUT-20200821-75SME-SMFE



I'm coming here because I'm not sure how to parse the error I'm getting. I don't recognize the lookup?s=... part of history.json, and I can get the ES futures product to work, but not this SM75. Any help is appreciated!
