S3 to Redshift: Unknown boolean format - json

Question

Executing a copy command from S3 to Redshift, loading JSON files. I have some fields as bool in a new table I'm inserting into and always getting the following error: "Unknown boolean format"
My JSON is well parsed, ran a million tests on that already. I've tried passing in the boolean fields as:
false // "false" // "False" // 0 // "0" // null
But always get the same error, when executing:
select * from stl_load_errors;
err_code err_reason
1210 Unknown boolean format
I've seen some comments about using IGNOREHEADER in my statement but that isn't an option because the files I'm dealing with are in a single row json format. Ignoring the head would basically mean not reading thefile at all. I have other tables working like this and work fine, but don't have any bool columns in those tables.

Answer 1

The COPY from JSON Format documentation page provides an example that includes a Boolean:
{
"id": 0,
"guid": "84512477-fa49-456b-b407-581d0d851c3c",
"isActive": true,
"tags": [
"nisi",
"culpa",
"ad",
"amet",
"voluptate",
"reprehenderit",
"veniam"
],
"friends": [
{
"id": 0,
"name": "Carmella Gonzales"
},
{
"id": 1,
"name": "Renaldo"
}
]
}
The Boolean documentation page shows values similar to what you have tried.
