Error: Provider produced inconsistent final plan

When expanding the plan for
module.deploy.aws_cloudfront_distribution.s3_distribution to include new
values learned so far during apply, provider
"registry.terraform.io/hashicorp/aws" produced an invalid new value for
.origin: planned set element
cty.ObjectVal(map[string]cty.Value{"connection_attempts":cty.NumberIntVal(3),
"connection_timeout":cty.NumberIntVal(10),
"custom_header":cty.SetValEmpty(cty.Object(map[string]cty.Type{"name":cty.String,
"value":cty.String})),
"custom_origin_config":cty.ListVal([]cty.Value{cty.ObjectVal(map[string]cty.Value{"http_port":cty.NumberIntVal(80),
"https_port":cty.NumberIntVal(443),
"origin_keepalive_timeout":cty.NumberIntVal(5),
"origin_protocol_policy":cty.StringVal("https-only"),
"origin_read_timeout":cty.NumberIntVal(30),
"origin_ssl_protocols":cty.SetVal([]cty.Value{cty.StringVal("TLSv1")})})}),

"origin_path":cty.NullVal(cty.String),
"origin_shield":cty.ListValEmpty(cty.Object(map[string]cty.Type{"enabled":cty.Bool,
"origin_shield_region":cty.String})),
"s3_origin_config":cty.ListValEmpty(cty.Object(map[string]cty.Type{"origin_access_identity":cty.String}))})
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.

script returned exit code 1

Expected Behavior

successful deployment

Actual Behavior

the first deployment succeeds, but subsequent deployments fail. If you change one of the custom_origin_config properties, the deployment will succeed, but the next deployments will fail with the same error.

Steps to Reproduce

1. terraform apply

All three of these look suspiciously similar: this bug, #24359, and #26743.
