resolve this by removing : 0

public static function encode($data, bool $prettyPrint = false): string
        {

       $encodedData = json_encode($data, $options);

Can you please help me with this

[pierrehilbert]

Unfortunately I'm not familiar with the APM Agent for PHP.
@intuibase should be able to help you.

[SergeyKleyman]

Hi @Arya-Aniket Could you please try the latest agent version. We fixed issue #1120 which is related to JSON encoding done by the agent.

[Arya-Aniket]

@SergeyKleyman I tried, but getting error while using page editor.

Receiving 0 at the end of every api response json.
