Common errors you’ll encounter with Handlebars

Just like any coding language, there are some common issues you might run into. Here’s a list to help you troubleshoot should you encounter issues.

Syntax Errors

Forgetting to close your Handlebars expressions
Misspellings in your partials or block expressions
Incorrect notation for your partials ({{@ partial}}) or if/where/each block expressions

Other Errors

If you see ‘null’ being printed in your templates, you aren’t properly null-checking values. Use an {if} expression to determine if the value exists before using it in a template
If you’re not successfully getting the attribute of data you want to show, make sure you’re aware of the evaluation context of the expression

Question 1 of 2

If you see 'null' being printed, what should you do?

Use an {if} expression to check if the value exists before using it

Handlebars can't handle missing data, so make sure you populate every attribute in your input data

Use a partial to inject data

Question 2 of 2

If you're getting errors about a partial not being available, what are some things you should check? (Select all that apply)

Determine if the partial is accessible to that template (i.e. in the same folder)

Check the spelling of the partial name

Make sure you have your syntax correct, ex. open and closing {{ }} and the > before the partial name
