I have an automation flow to send an email automatically, with information from a box in google sheet.
This is the box on google sheet.
In it there is a column called “correo”.
That parameter is recognized by my flow.
But the GMAIL module is not, because I get BundleValidationError: Missing value of required parameter ‘to’.
How can I solve that error? 
Welcome to the Make community!
It appears that the trigger module might not be getting the data correctly.
Can you go back to your scenario run History and see what is coming out of the output bundle?
Please export the scenario blueprint file to allow others to view the mappings and settings. At the bottom of the scenario editor, you can click on the three dots to find the Export Blueprint menu item.
(Note: Exporting your scenario will not include private information or keys to your connections)
Uploading it here will look like this:
blueprint.json (12.3 KB)
Please provide the output bundles of the modules by running the scenario, then click the white speech bubble on the top-right of each module and select “Download output bundles”.
Save the bundle contents in your text editor as a bundle.txt file, and upload it here into this discussion thread.
Uploading it here will look like this:
bundle.txt (12.3 KB)
If you are unable to upload files on this forum, alternatively you can paste the formatted output bundle in this manner:
Either add three backticks ``` before and after the code, like this:
```
input/output bundle content goes here
```
Or use the format code button in the editor:
Providing the output bundles will allow others to replicate what is going on in the scenario even if they do not use the external service.
Following these steps will allow others to assist you here. Thanks!
