Express JS TypeError: Cannot read properties of undefined (reading 'id') - postgresql

Question

I am trying to build a database query with express js to get a recipe from a table that joins a recipe's information with specific ingredients from a third table.
The query I have works fine with pgadmin and postman when I am not specifying the id from my recipes table on which the join occurs but when I try and specify the recipe.id to return just one recipe and ingredients I get this error:
TypeError: Cannot read properties of undefined (reading 'id')

Here is the express js query:
app.get('/getjoinedrecipes', (req, res) => {
console.log(req, res)
pool
.query(
'select * from ingredientrecipes inner join recipes on ingredientrecipes.recipe_id = recipes.id inner join ingredients on ingredientrecipes.ingredient_id = ingredients.id',
[req.body.recipes.id]
)
.then((result) => {
res.status(200).send(result.rows)
})
.catch((error) => {
console.log(error)
res.status(500).send(error)
})
})
Here is the body I am sending to http://localhost:3001/getjoinedrecipes via postman for testing:
{
"id": 8
}
