Embedded json in pipeline template causing format errors

[bhavith]

We have an embedded json in the pipeline template yaml. When we run terraform plan, I am getting an error :
"data.template_file.pipeline_template: data.template_file.pipeline_template: failed to render : <template_file>:252,84-85: Invalid character; Single quotes are not valid. Use double quotes (") to enclose strings., and 94 other diagnostic(s)"

I tried to escape the single quotes, using /' which gave me the error: "data.template_file.pipeline_template: data.template_file.pipeline_template: failed to render : <template_file>:252,84-85: Invalid character; This character is not used within the language., and 100 other diagnostic(s)"

Hello,

is there any solution to make this work with the terraform v0.12.19 and a v2 template provider?
