Always validate your JSON-LD.
If is static JSON-LD that is generated directly in the HTML server-side, you can use a JSON-LD validator that accepts a link to your page.
It will tell you what schemas it can see, and report on their validity.
If your JSON-LD is generated dynamically by client-side script, these tools may not be able to see the result, however you can use Chrome Dev Tools top copy the generated JSON-LD from your page, and paste that into the tool for validation.
Google Search Console also does a good job of reporting on what JSON-LD it finds in each page, and whether it encounters any problems.
