issue.update(fields={'fixVersions':[{'name':current_fixVs[0]},{'name':current_fixVs[1]},{'name':current_fixVs[2]},{'name':current_fixVs[3]}]})considering 4 fix versions the above code works without overwriting(acutally overwrites) existing because I fetch the existing fixversion and append(otherwise it overwrites) to the array.
But I cannot keep updating the code by adding another element from the array - current_fixVs[4] as the number of fix versions will dynamically change. Also, the api won't accept a single array(containing all fixversions) to be added as fixversion.
