Error: failed to decode PEM block containing private key of type "unknown"

Terraform
1

I am converting my working build.tf script into several json equivalents resource.tf.json, data.tf.json, variable.tf.json, output.tf.json, terraform.tf.json, and provider.tf.json - so, one .tf.json file for each block type. I’m down to my LAST error which has thus far proved insurmountable. In my build.tf file the data block syntax that works is …

data “tls_public_key” “public_key” {
private_key_pem = file("${path.root}/keys/ssh_key.pem")
}

The equivalent data.tf.json syntax that does not work is …

{
“data”: {
“tls_public_key”: {
“public_key”: {
“private_key_pem”: “file(’${path.root}/keys/ssh_key.pem’)”
}
}
}

With the .tf.json files initialised, terraform plan and also terraform apply throw the same response … Error: failed to decode PEM block containing private key of type “unknown”.

If I initialise the build.tf file then plan and apply work without error.

Thanks in anticipation of any assistance. Stuart

Update. Fixed. Specific data.tf.json syntax that worked was …

{
“data”: {
“tls_public_key”: {
“public_key”: {
“private_key_pem”: “{file(\"{path.root}/keys/ssh_key.pem”)}"
}
}
}

Yay! Cheers. Stuart
