### Terraform Version ``` Terraform v0.12.1 + provider.datadog v1.9.0 ``` ### Terraform Output No configs except for the standard boilerplate ones. Same for `terraform show` and `terraform state show` ```hcl # module.datadog.datadog_timeboard.alexiss-timeboard-6-jun-2019-1341: resource "datadog_timeboard" "alexiss-timeboard-6-jun-2019-1341" { id = "1234573" title = "Alexis's Timeboard 6 Jun 2019 13:41" graph { autoscale = true events = [] group = [] include_no_metric_hosts = false include_ungrouped_hosts = false precision = "2" scope = [] style = {} title = "Avg of system.load.1 over *" viz = "query_value" yaxis = {} request { aggregator = "avg" increase_good = false q = "avg:system.load.1{*}" stacked = false style = {} } } } ``` `terraform show -json | jq .` (The most complete) ```json { "format_version": "0.1", "terraform_version": "0.12.1", "values": { "root_module": { "child_modules": [ { "resources": [ { "address": "datadog_timeboard.alexiss-timeboard-6-jun-2019-1341", "mode": "managed", "type": "datadog_timeboard", "name": "alexiss-timeboard-6-jun-2019-1341", "provider_name": "datadog", "schema_version": 0, "values": { "description": "", "graph": [ { "autoscale": true, "custom_unit": "", "events": [], "group": [], "include_no_metric_hosts": false, "include_ungrouped_hosts": false, "marker": [], "node_type": "", "precision": "2", "request": [ { "aggregator": "avg", "change_type": "", "compare_to": "", "conditional_format": [], "extra_col": "", "increase_good": false, "order_by": "", "order_direction": "", "q": "avg:system.load.1{*}", "stacked": false, "style": {}, "type": "" } ], "scope": [], "style": {}, "text_align": "", "title": "Avg of system.load.1 over *", "viz": "query_value", "yaxis": {} } ], "id": "1234573", "read_only": null, "template_variable": [], "title": "Alexis's Timeboard 6 Jun 2019 13:41" } } ], "address": "module.datadog" } ] } } } ``` For the truncation issue, here is the first missing embedded resource from the output of `terraform plan` Three total graphs were lost. The missing graphs get transformed into the next graph in the series. The missing graphs are missing in all versions of the `show`: ``` ~ graph { autoscale = false - events = [] -> null - group = [] -> null include_no_metric_hosts = false include_ungrouped_hosts = false - scope = [] -> null style = {} ~ title = "Memory Rollup" -> "Available Swap" viz = "timeseries" yaxis = {} ~ request { increase_good = false ~ q = "max:system.mem.slab{$host}, max:system.mem.buffered{$host}, max:system.mem.cached{$host}, max:system.mem.free{$host}, max:system.mem.shared{$host}, max:system.mem.paged{$host}, max:system.mem.page_tables{$host}, max:system.mem.nonpaged{$host}, max:system.mem.committed{$host}" -> "avg:system.swap.free{$host}, avg:system.swap.used{$host}" stacked = false ~ style = { - "palette" = "dog_classic" -> null - "type" = "solid" -> null - "width" = "normal" -> null } - type = "area" -> null } - request { - increase_good = false -> null - q = "max:system.mem.total{$host}" -> null - stacked = false -> null - style = { - "palette" = "warm" - "type" = "dashed" - "width" = "normal" } -> null - type = "line" -> null } } ``` ### Debug Output Not including - no errors or complaints ### Expected Behavior `terraform show`, `terraform show -json`, and `terraform state show ADDR` should all show the same (complete) information ### Actual Behavior `terraform show`: Strips null and empty string fields, but leaves empty lists and maps `terraform show -json`: Shows null, empty string, etc., but no way to differentiate a list from a repeated embedded block `terraform state show ADDR`: same as `terraform show` All: Occasional complete lost of embedded blocks (consistent between formats) ### Steps to Reproduce Cannot give exact steps for data loss beyond output shown above. Discovered while using datadog, so steps will specify there 1. Create a datadog timeboard with one graph 2. Create a stub resource block to bind the import to 3. `terraform init` 4. `terraform import datadog_dashboard.stub ID` 5. `terraform show`, `terraform show -json`, and `terraform state show datadog_dashboard.stub` ### Additional Context Using `terraform import` and `terraform show` to generate configs that can allow management of existing resources ### References Seems similar to: https://github.com/hashicorp/terraform/issues/20028
