handle exceptions when using already deployed functions on DiSARM OpenFaas #9
Description
@ric70x7 could you try out a version of the disarm-gears code with e.g. a completely wrong URL included, and see what happens in one of the functions that uses it? (e.g. fn-prev-predictor). If it's clear in the return to the user running the fn-prevalence-predictor (and ideally, the logs) that there was an error in another function, then think we're ok. If the error message is blank, or ambiguous, we might need to add some more exception handling (try:... except:...) around network requests.
