Yasha .json template error

I have a valid .json file that works if I use it as is. This .json file has {{ .foo }} variables in it, which are internally processed ( these are not jinja variables) .

I am attempting to take this .json file and run it through the Yasha template command to create more .json files using jinja {{ bar }} to replace other hard coded variable values in the .json file.

If I run the .json file as is, it complains about the .json {{ .foo }} variables as expected. These variables can not be replaced or removed so I used the {% raw %} as described here to omit them.

My syntax looked like this: {% raw %} ...code line...{{ .foo } }...more code...{% endraw %}.

This should have allowed Yasha to ignore the .json variables with no complaints. Instead I receive the following error:

I think this is because a json validator is being run on the file first, before jinja is used. I didn’t expect any json validating.

If I change the file extension from .json to .txt it has no complaints and completes its jinja parsing correctly. I think because there is no json validating in this file extension.

This should be fixed in 4.1. Thanks for reporting.

Yasha does not validate the template.
