I keep getting this error: TypeError: Cannot read properties of undefined (reading 'lab'), although the input name is correct:

This is the html code of the file input:

Lab Results

placeholder=<%=info.patient_labResults %>>

Options

href="/api/deleteLab?id=<%=info.patient_id%>">Delete

This is the code for the post method (using knex) =>

exports.editLabResults = async (req, res) => {

const { labResultsName, labResults } = req.files.lab;

console.log(labResultsName);

if (labResultsName && labResults) {

console.log(labResultsName);

await knexClient.insert({ patient_labResultsName: labResultsName, labResults: labResults })

.into('patients')

.where('patient_id', id);

res.sendStatus(200);

} else {

console.log("Empty");

res.sendStatus(400);

}

}
