Template Config has invalid expression
Hi,
I would like to send users a welcome email when they log into my app. I am using the Sendgrid API and I am trying to build a node which takes the user name and email address as inputs.I then would like pass on the value of the name input to the name variable in my dynamic template.
The node works when I dont use the input value and hardcode the name, but when I try to set the template variable to the input field I get an error: "Template Config has invalid expression"
Any suggestions on how I could fix this?

When encountering the "Template Config has invalid expression" error in your node, it typically indicates an issue with how the template variable is being set. This error often occurs when the expression used to reference the input variable is incorrect or not evaluated as expected.
Here are a few suggestions to address this:
1. Check Expression Syntax: Ensure that the expression to access the input field is correct. For example, if you are using a dynamic template, ensure the variable names match exactly with what's expected in your SendGrid template.
2. Correct Input Variables: Make sure the input variable names used in your node match those defined in your SendGrid template. If there's a mismatch, you'll need to update one to match the other.
3. Variable Evaluation: If you're using BuildShip, ensure your nodes and expressions evaluate correctly to pass the value from the input to your template. You might require a custom expression or script to make this work.
4. Debug Log: Check any logs or debugging information available to see how variables are being interpreted. This might provide insights into where the breakdown occurs.
If these suggestions do not resolve the issue, it might be beneficial to seek further assistance through BuildShip's in-app support to investigate the specific expression and configuration used in your node.
If you need more detailed guidance on setting up dynamic templates with SendGrid or any other component, it might be worthwhile to consult the SendGrid API documentation or reach out to their support for help specific to the API usage.
