How to insert JSONB parameter in Postgres Action

Hiya folks,
Can't see what I'm missing here. I have a Postgres action as below:

-- $1 data

INSERT INTO table (data)
VALUES (cast($1 as jsonb));

-- $1 data

INSERT INTO table (data)
VALUES (cast($1 as jsonb));

-- $1 data

INSERT INTO table (data)
VALUES (cast($1 as jsonb));

-- $1 data

INSERT INTO table (data)
VALUES (cast($1 as jsonb));

but I get

ExecutionErr: error during execution of the script: db error: ERROR: unsupported jsonb version number 39

ExecutionErr: error during execution of the script: db error: ERROR: unsupported jsonb version number 39

ExecutionErr: error during execution of the script: db error: ERROR: unsupported jsonb version number 39

ExecutionErr: error during execution of the script: db error: ERROR: unsupported jsonb version number 39

VALUES ($1::JSONB)

VALUES ($1::JSONB)

VALUES ($1::JSONB)

VALUES ($1::JSONB) doesn't work either.
The parameter I'm using (e.g.

'{"some": "data"}'

'{"some": "data"}'

'{"some": "data"}'

'{"some": "data"}' works directly in the query:

INSERT INTO table (data)
VALUES ('{"some": "data"}');

INSERT INTO table (data)
VALUES ('{"some": "data"}');

INSERT INTO table (data)
VALUES ('{"some": "data"}');

INSERT INTO table (data)
VALUES ('{"some": "data"}');

Windmill expects a

string

string

string

string type as the parameter.
I've checked the docs but couldn't find anything.
Thaaanks!
