Hello @Robert Cemper

Thank you for your answer, you were right. 

I have modified my Dockerfile in order to replace this line:

ARG IMAGE=intersystemsdc/iris-community

for this one:

ARG IMAGE=intersystems/iris-ml-community:2023.1.0.235.0

And now works!!

Thank you for your quick response.  👏

P.D.: I think that definitely I have a good excuse to change mi old computer... 😜

I answer my self xD

##class(%SYSTEM.Encryption).MD5HashStream(stream)

I hope it can be useful for someone too xD

Thanks!
