My current config is completely failing. Terraform apply fails on genesyscloud_flow resource with 400 Bad Request. Sydney region. Provider v1.18.
{
"type": "IVR",
"settings": {
"maxWaitTime": 30,
"greetingAudio": "https://example.com/welcome.wav"
}
}
API rejects maxWaitTime. Schema expects integer but TF sends float? Or is the endpoint deprecated?
The quickest way to solve this is to ensure the maxWaitTime value is explicitly cast as an integer in your Terraform configuration. The Genesys Cloud API schema for IVR settings is strict regarding data types, and while Terraform often handles type coercion, the genesyscloud_flow resource can sometimes pass floating-point values if the variable definition allows it. This triggers the 400 Bad Request because the backend expects a pure integer for duration fields.
From an AppFoundry integration perspective, we frequently see this issue when teams migrate configurations from manual JSON edits to Infrastructure as Code. The maxWaitTime field specifically requires an integer representing seconds. If your variable is defined as number without a constraint, Terraform might infer a float like 30.0 from other parts of your pipeline or default values.
Update your Terraform variable definition to enforce the integer type:
variable "ivr_max_wait_time" {
type = number
default = 30
}
# In your resource block
resource "genesyscloud_flow" "example" {
name = "IVR Flow"
# Ensure explicit casting if using dynamic values
settings = jsonencode({
maxWaitTime = floor(var.ivr_max_wait_time)
greetingAudio = "https://example.com/welcome.wav"
})
}
Using jsonencode with floor() guarantees that the payload sent to the API is a clean integer. Additionally, verify that the greetingAudio URL is publicly accessible or whitelisted in your BYOC edge configuration if you are using private assets. The Sydney region endpoints are fully supported in provider v1.18, so the issue is almost certainly the payload structure. Check the API documentation for the IVR schema to confirm all nested fields match the expected types exactly.
The official documentation states the schema rejects any value with a decimal point, so explicit casting is the only reliable fix.
Try forcing the type in your variable definition to avoid Terraform’s automatic float inference.
variable max_wait { type = number } becomes variable max_wait { type = string } and pass "30" directly.
The way I solve this is by ensuring the JSON payload strictly adheres to integer types before sending it through the API. In my load tests, even slight type mismatches cause immediate 400 errors, which breaks the flow execution. The suggestion above about casting is spot on. Terraform sometimes infers floats if the variable isn’t explicitly defined as an integer. Try using the int() function in your Terraform code to force the value.
max_wait_time = int(var.max_wait)
Also, verify that the greetingAudio URL is publicly accessible. The API might reject the payload if it can’t validate the audio file during the initial schema check. This often gets overlooked when focusing on data types. Check the API documentation for the specific IVR schema version you are using, as some fields have changed in recent provider updates.
