failed to parse hook response...

[baierDev]

Question I want to show (send) the actual "processing-state" of a pre-finish-hook to the client... How I make this to work ?

In my test-setup, i try to "simulate" a processing time with simple delay...

pre-finish file:

#!/usr/bin/env python3
import time

print('start processing')
time.sleep(5)
print('processing finished')

The tusd-log show me:

The stdout from hooks is parsed as JSON, so it expects a JSON object to be printed to stdout. If you want to log something, you should write that to stderr.

OK, thank you!

Can you give me a simple "static" code-sample how the python script (object) should look like ?

This has no errors, but how to read the output on client ?

#!/usr/bin/env python3
import time,json

msg1 = {"body":"start processing"}
msg2 = {"testmessage":"processing finished"}

y1 = json.dumps(msg1)
y2 = json.dumps(msg2)

print(y1)

time.sleep(5)

Please have a look at https://github.com/tus/tusd/tree/main/examples and https://github.com/tus/tusd/blob/main/docs/hooks.md#common-uses for examples.
