Unusual error when adding new record using simple API call

Hi all,

I believe this is a bug. Very unusual behaviour attempting to add a new record to this table. All fields are spelt correctly. Unsure to why its returning this error. Any feedback would be welcome.

code: ERROR_CODE_INPUT_ERROR,
message: Invalid method for filter - trim,
param: user_id

Thanks,
Michael
