Source is not valid JSON if key is not present

[Razvan_Dragulescu]

Hi guys! I’m trying to parse using JSON module using map() to search metaData for entries where “key” is “_sameday_shipping_locker_id” and returning the associated “value” but if “_sameday_shipping_locker_id” isn’t present, I would like the outputs to be “{}” no value.

The JSON module parses the code successfully if “_sameday_shipping_locker_id” is present but if it’s not present it returns “DataError
Source is not valid JSON.”

What am I missing?
Thanks a lot!

You probably forgot to use the get or first function around the map function.

You are currently doing an ifempty directly on an array of values, which is incorrect.

For more information, see Mapping with arrays below.
