Got a Python PCF processing code aand I ran it against a message generated with the following subscription. I get the following error. I thought is was the BYTE/STRING issue in Python. I tried converted to string but got an issue at byte 44.

Code:

It would be helpful in your question to say what your PCF processing code did.

Anyway, you appear to have given us a PCF format response message in your question. The message body you have given us:
Code:
msg": {"body": "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"}


decodes as follows:

[   64 bytes] Integer (MQCFIN)

Value        :1587 [0x'633']
[   48 bytes] Integer (MQCFIN)
Parameter Id :12
Value        :5232 [0x'1470']
[   32 bytes] Integer (MQCFIN)
Parameter Id :7
Value        :113 [0x'71']
[   16 bytes] Integer (MQCFIN)
Parameter Id :8
Value        :113 [0x'71']


So from this I can now deduce that you are using the published stats from the queue manager - equivalent to using amqsrua.

This is not a string message - so I am not surprised that converting it to a string had issues. This is a PCF message, but you knew that because that was the first line of your question. If you have PCF processing code in your Python app, you need to apply that code to the PCF message body.

Cheers,
Morag

how did you decode it. You did not say. Colin P's Python script has an issue with it.

For PCF I prefer to use Java. Makes things so easy with the com.mq.header.pcf classes... using PCFMessageAgent...

I just copied it into MQEdit.
