YAJL FREE RPGLE (error Parsing data Json)

Question

I am having problems when using the YAJL tool. when moving data from IFS data to docnode (yajl), and I tried to debug the program, the docnode field contained DOCNODE SPP:000000080088ADC10.

while the data in the STMF is {"code":400,"errors":[{"code":400,"details":"invalid signature","message":"Bad Request"}],"message":"bad.request","responseTime":"20240424070955"}

this my complete code : H DFTACTGRP(*NO) Option(*SrcStmt : *NoDebugIO)
H BNDDIR('HTTPAPI')
H BNDDIR('YAJL')
