bid_amount_local_micro not allowing NULL


While creating a line_item, the documentation says about “bid_type”

If set to AUTO, bid_amount_local_micro must be NULL.

However when bid_amount_local_micro is sent as NULL. This error pops up:

Have you tried omitting bid_amount_local_micro=NULL? By omitting it, you are not setting it to anything, which is what you are after here - I do admit the documentation isn’t entirely clear! Let us know if this does the trick for you.
