Hi team, I tried to develop a provider using SetNestedAttribute, but when I executed terraform apply, I got an error. I tried for a long time but couldn’t figure out why this happened.
Error: Provider produced inconsistent result after apply
When applying changes to example_set_nested.test01, provider "provider[\"test.com/test/example\"]" produced an unexpected new value:
.set_nested: planned set element cty.ObjectVal(map[string]cty.Value{
"enable_gateway":cty.False,
"fixed_ip":cty.StringVal("127.0.0.1"),
"fixed_ip_v4":cty.NullVal(cty.String),
"mac":cty.NullVal(cty.String),
"port":cty.NullVal(cty.String),
"uuid":cty.StringVal("123")
})
does not correlate with any element in actual.
This is a bug in the provider, which should be reported in the provider's own issue tracker.
Sample code using SetNestedAttribute

SetNestedResourceModel struct {
Id types.String `tfsdk:"id"`
SetNested types.Set `tfsdk:"set_nested"`

main.tf.json
{
"resource": {
"example_set_nested": {
"test01": {
"set_nested": [
{
"uuid": "123",
"fixed_ip": "127.0.0.1"
}
]
},
"test02": {
"set_nested": [
{
"uuid": "234",
"enable_gateway": true
}
]
}
}
}
}
Command line output of executing terraform apply, I found that the output of “test01” and “test02” are different, “test01” does not display “fixed_ip_v4”, “mac”, “port”, I think “test01” should display these contents. Although the execution failed, the data was correctly written into the tfstate file.
And then, I modified the main.tf.json file, added " “enable_gateway”: true " in “test01”, and executed terraform apply again and got the correct result.
I am very confused now. I think whether I add “enable_gateway” in “main.tf.json” or not, the execution result should be the same.
Can someone answer this question? Thanks.
