@Roy-Mustang thank you
FingerprintPluginV10 engine: POST /scripts/FingerprintPluginV10/last/data returns 502 Bad Gateway
-
playwright-with-fingerprints v1.6.3 (engine 27.8.1, script FingerprintPluginV10)
fails on every plugin.fetch() with "Json parse error : illegal value".Root cause found (verified by MITM capture + direct requests from our machine):
The engine script POSTs to
https://bablosoft.com/scripts/FingerprintPluginV10/last/data
(multipart/form-data, fields: email, scriptsign) during startup and expects a
JSON response. The server currently responds:HTTP/1.1 502 Bad Gateway
Server: nginx/1.18.0 (Ubuntu)
<html><head><title>502 Bad Gateway</title>...The engine then fails to JSON.parse() this HTML page, producing
"Json parse error : illegal value".Direct reproduction from our side (same endpoint, same POST):
3 attempts -> 502, 502, 502 (latency 18.7s / 1.0s / 19.3s - backend unstable).Other service endpoints are healthy: /checkkey returns valid:true,
/preview returns valid fingerprint JSON.This looks like a server-side (nginx upstream) outage on your side, affecting
all users of the plugin, not specific to our key/IP (key is valid, IP is
whitelisted).
