Error with Parallel Processing Toolbox

We are experiencing a problem with regard to the parallel processing toolbox, while querying the data in parallel using ‘parfor’; while we are able to query the database and read the data using ‘fetch’ command though when we try to run the code in parallel; it throws an error ‘Invalid function’

Does anyone have seen something similar?

Does this happen for all PARFOR loops? Are there any reproduction steps that we can try?
