Get encoding error in both phpSample_Air_LFS_Dynamic_Xml.php & phpSample_Air.php

[team-techchef]

I am trying to integrate galileo and start with search, so i was trying phpSample_Air.php but got the following error

[08-Dec-2022 20:18:33 UTC] PHP Fatal error: Encoding Error! in /template/api/archive-flight.php on line 108

Then i try with phpSample_Air_LFS_Dynamic_Xml.php but still getting the same error as specified below

[08-Dec-2022 20:33:34 UTC] PHP Fatal error: Uncaught Exception: Encoding Error! Check SOAP Fault in /template/api/archive-flight.php:285
Stack trace:
#0 /template/api/archive-flight.php(229): parseOutput()

Then i tried the steps you've guided in this thread, #215

1. I have changed the schema
2. I have also updated the date in schema as specified here <air:SearchDepTime PreferredTime="2019-08-27">
   But still same error comes

Then i check my user credentials here, https://demo.travelportuniversalapi.com/Home
and found credentials are fully fine.

Need your help to proceed further.
