Issue Details

When the Python Node receives a positive error code, the Python Node's return value will always be the default value used in the input of its Return Type. How can this issue be resolved and have the Python Node return the correct value?

Solution

NI R&D has verified this as a bug with Bug Number 3948489. As a temporary workaround, please clear the positive error before connecting the error wire to the Python Node by using Clear Errors VI.
