500 Internal Server Error?

Hey there,

I’m not sure this is necessarily the best place to post this so apologies for that, but I have a Terraform script which creates a VPC, GKE Deployment, and an Ingress to said deployment.

The script itself has been working, but since last night everytime I try to run a plan and apply, I get a 500 Internal Server Error. Specifically:

 Error: an error on the server ("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\"> \n<html xmlns=\"http://www.w3.org/1999/xhtml\"> \n<head> \n<title>IIS 10.0 Detailed Error - 500.19 - Internal Server Error</title> \n<style type=\"text/css\"> \n<!-- \nbody{margin:0;font-size:.7em;font-family:Verdana,Arial,Helvetica,sans-serif;} \ncode{margin:0;color:#006600;font-size:1.1em;font-weight:bold;} \n.config_source code{font-size:.8em;color:#000000;} \npre{margin:0;font-size:1.4em;word-wrap:break-word;} \nul,ol{margin:10px 0 10px 5px;} \nul.first,ol.first{margin-top:5px;} \nfieldset{padding:0 15px 10px 15px;word-break:break-all;} \n.summary-container fieldset{padding-bottom:5px;margin-top:4px;} \nlegend.no-expand-all{padding:2px 15px 4px 10px;margin:0 0 0 -12px;} \nlegend{color:#333333;;margin:4px 0 8px -12px;_margin-top:0px; \nfont-weight:bold;font-size:1em;} \na:link,a:visited{color:#007EFF;font-weight:bold;} \na:hover{text-decoration:none;} \nh1{font-size:2.4em;margin:0;color:#FFF;} \nh2{font-size:1.7em;margin:0;color:#CC0000;} \nh3{font-size:1.4em;margin:10px 0 0 0;color:#CC0000;} \nh4{font-size:1.2em;margin:10px 0 5px 0; \n}#header{width:96%;margin:0 0 0 0;padding:6px 2% 6px 2%;font-family:\"trebuchet MS\",Verdana,sans-serif; \n color:#FFF;background-color:#5C87B2; \n}#content{margin:0 0 0 2%;position:relative;} \n.summary-container,.content-container{background:#FFF;width:96%;margin-top:8px;padding:10px;position:relative;} \n.content-container p{margin:0 0 10px 0; \n}#details-left{width:35%;float:left;margin-right:2%; \n}#details-right{width:63%;float:left;overflow:hidden; \n}#server_version{width:96%;_height:1px;min-height:1px;margin:0 0 5px 0;padding:11px 2% 8px 2%;color:#FFFFFF; \n background-color:#5A7FA5;border-bottom:1px solid #C1CFDD;border-top:1px solid #4A6C8E;font-weight:normal; \n font-size:1em;color:#FFF;text-align:right; \n}#server_version p{margin:5px 0;} \ntable{margin:4px 0 4px 0;width:100%;border:none;} \ntd,th{vertical-align:top;padding:3px 0;text-align:left;font-weight:normal;border:none;} \nth{width:30%;text-a") has prevented the request from succeeding (get ingresses.networking.k8s.io srn-tester0-ingress)

The only relevant information I can gather from it is “an error on the server IIS 10.0 Detailed Error - 500.19 - Internal Server Error has prevented the request from succeeding” which really does not tell me much.

Has anyone run into a similar issue or have any advice on how I could go about fixing it?
