Why Terraform try to destroy resource that been imported?

[niraj06]

We have terraform module to create a google big query tables, using that module we try to import the table, so far good but, when we try to "terraform apply" it's trying to delete the import table and plan to re-create it.
This is a message in the console that will be destroyed

(because resource uses count or for_each)

Yes, the module has for_each been used, don't understand why it's forcing to drop resources?

resource "google_bigquery_table" "default" {
for_each = local.tables
project = each.value.project_id
dataset_id = each.value.dataset_id
table_id = each.key
friendly_name = each.value.friendly_name
description = each.value.description
clustering = try(each.value.options.clustering, null)
expiration_time = try(each.value.options.expiration_time, null)
labels = each.value.labels
schema = file(each.value.schema)

dynamic "encryption_configuration" {
for_each = try(each.value.options.encryption_key, null) != null ? [""] : []
content {
kms_key_name = each.value.options.encryption_key
}
}

dynamic "range_partitioning" {
for_each = try(each.value.range_partitioning, null) != null ? [""] : []
content {
field = each.value.range_partitioning.field
range {
start = each.value.range_partitioning.start
end = each.value.range_partitioning.end
interval = each.value.range_partitioning.interval
}
}
}

dynamic "time_partitioning" {
for_each = try(each.value.time_partitioning, null) != null ? [""] : []
content {
expiration_ms = each.value.time_partitioning.expiration_ms
field = each.value.time_partitioning.field
type = each.value.time_partitioning.type
}
}
deletion_protection = "true"

lifecycle {
ignore_changes = [
encryption_configuration
]
}
}

I ran into this same issue when trying to import AWS ECR repositories. In my case the issue was that the way you import resources defined using count or for_each use a different syntax compared to importing a resource that defines a single entity.

Using this syntax caused terraform to delete and recreate the ECR repo after the import:
terraform import module.ecr_repositories.aws_ecr_repository.repository test/repository/abc

Using this syntax imported the resource successfully and did not cause the deletion and recreation issue:
terraform import 'module.ecr_repositories.aws_ecr_repository.repository["test/repository/abc"]' test/repository/abc

You can find the documenation of this syntax at the bottom of the page: https://www.terraform.io/cli/commands/import

Hopefully this helps!

@NathanMcK95 has likely covered it! If that doesn't address it, can you attach a plan output here so we can diagnose the issue?

It's possible for some resources that import will result in a resource missing information, if APIs don't return user-defined values.
