Adobe Export PDF API gives asset not found error, but pdf file successfully uploaded to uploadURI

I used 'https://pdf-services-ew1.adobe.io/assets', and got following response:

{
    "uploadUri": "https://dcplatformstorageservice-prod-eu-west-1.s3-accelerate.amazonaws.com/16a9de6d208743239d1f694295f12626_254127B763EDC88B0A495FC7%40techacct.adobe.com/471bc6c7-d837-4817-891c-7d042b3025b6?X-Amz-Security-Token=FwoGZXIvYXdzEP%2F%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEaDIaZ0FfEsaBPTEBY9yLUATxRYzDjDFilQARDSnyOSy2XdBy%2FoL2cLd5OacEA%2FWLosaEJ75p%2BeOwO0ITohEt14Tw7gCamc7OBXD1CR3%2B4tt1%2BT3iM6FT5KwYoFlcyWN00WNg53eWaRrKAqeaZYAOYG6r6BNaZLSx9eMf4KX8audyoDX3ZLrvu9XSQtkBLAzlC5hab0C5voHrGXhwKo6jVMZV1Fea0KQZ7nACQ3woWJ6FdjEgPijk0RDwk3KjpLTnc9IU%2B%2F1AdmcaJ5ozJ0%2B8OUoiluWGS14OPMoD%2FeDlnBOCsSnuvKPD0xp8GMi01KKrkxRzzmVb0nXgyk2vE2dlkWoCk9XT%2FGkeIQdSVrU9QFLfLxtHgF4qeIvU%3D&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20230219T061237Z&X-Amz-SignedHeaders=content-type%3Bhost&X-Amz-Expires=3600&X-Amz-Credential=ASIAWD2N7EVPIZMO5LHX%2F20230219%2Feu-west-1%2Fs3%2Faws4_request&X-Amz-Signature=f344cf4421eb34e9aaa7815d21714b1722b39c031d176567ce32ab0094d472f8",
    "assetID": "urn:aaid:AS:EW1:22f40021-93ab-4c3d-a8de-93d4e68de622"
}

Then I did a put request to the resigned URI, and uploaded the file in body in binary in postman.

This request gave 200 OK response.

But after this when I am using 'https://pdf-services-ue1.adobe.io/operation/exportpdf' API, it gives response:

{
    "error": {
        "code": "NOT_FOUND",
        "message": "Asset Not Found."
    }
}

How to resolve this issue?
