Hi, I work on a community provider:
I have an issue with the error Error: Provider produced inconsistent final plan as described in:
The proposed solution is to define a CustomizeDiff function, but i cannot get this to work.
My main issue comes because its common to use heredoc to define some of the unstructured json I encounter for some resources. In the trivial example below the rule resource will always produce an unexpected plan if the site resource doesn’t already exist:
Error: Provider produced inconsistent final plan
When expanding the plan for pingaccess_rule.acc_test_rule_bar to include new
values learned so far during apply, provider "pingaccess" produced an invalid
new value for .configuration: was cty.StringVal(""), but now
cty.StringVal("\t\t{\n\t\t\t\"cidrNotation\":
\"127.0.0.5/32\",\n\t\t\t\"negate\": false,\n\t\t\t\"overrideIpSource\":
false,\n\t\t\t\"headers\": [],\n\t\t\t\"headerValueLocation\":
\"LAST\",\n\t\t\t\"fallbackToLastHopIp\": true,\n\t\t\t\"errorResponseCode\":
404,\n\t\t\t\"errorResponseStatusMsg\":
\"Forbidden\",\n\t\t\t\"errorResponseTemplateFile\":
\"policy.error.page.template.html\",\n\t\t\t\"errorResponseContentType\":
\"text/html;charset=UTF-8\",\n\t\t\t\"rejectionHandler\":
null,\n\t\t\t\"rejectionHandlingEnabled\": false\n\t\t}\n").
This is a bug in the provider, which should be reported in the provider's own
issue tracker.
resource "pingaccess_site" "demo" {
name = "demo"
targets = ["localhost:4321"]
max_connections = -1
max_web_socket_connections = -1
availability_profile_id = 1
}
resource "pingaccess_rule" "demo_2" {
class_name = "com.pingidentity.pa.policy.CIDRPolicyInterceptor"
name = "demo_2"
supported_destinations = [
"Site",
"Agent"
]
configuration = <<EOF
{
"cidrNotation": "127.0.0.${pingaccess_site.demo.id}/32",
"negate": false,
"overrideIpSource": false,
"headers": [],
"headerValueLocation": "LAST",
"fallbackToLastHopIp": true,
"errorResponseCode": 403,
"errorResponseStatusMsg": "Forbidden",
"errorResponseTemplateFile": "policy.error.page.template.html",
"errorResponseContentType": "text/html;charset=UTF-8",
"rejectionHandler": null,
"rejectionHandlingEnabled": false
}
EOF
}
I have tried using a CustomizeDiff to catch this but with no luck:
CustomizeDiff: customdiff.ComputedIf("configuration", func(diff *schema.ResourceDiff, meta interface{}) bool {
return diff.HasChange("configuration")
}),
Any suggestions would be greatly appreciated.
