error converting typed value TypedValue[it=1134

Try removing this character from your text "®"

Remove "®" special character from "AmBisome®"  it cannot be properly converted to XML format.
Additionally, check the multiple null values in your data. Ensure all required fields have default values instead of nulls before form submission.

The comments above about the special character are almost certainly on-point.

To help accomplish this, I would recommend sanitizing user input (particularly when it's more likely than normal to be copy-pasted from external fields) through the clean() function, which strips out all non-printable characters and is supposed to remove characters that would cause issues when inserting into the DB.
