Bit of background first; the ContractAPI that is available in Java, Go and Typescript is used to generate a 'model' of the overall contract including the data type that be passed and returned from transaction functions. (JavaScript supports a limited subset to the extent possible based on it's typing).

In order to support this there has to be a 'serializer' of some sort to process the data. The underlying chaincode API of just 'invoke(byte[]): byte[]' gives the developer the power to serialize how they wish though not all of us need to use that power.

There is a default 'serializer' in the ContractAPI; this can be swapped out if needed.

To specifically answer the question;

The return types can be:

• strings,
• numbers (for Java this is any of the primitive 'number' types)
• booleans,
• other types that have been annotated.
• arrays of the above

For the 'other types', there are annotations that can be used to define types that can also be passed to and from the transaction functions.

You might see something like this:

We can use os module to create the pip list, then we use pandas.read_csv with \s+ as seperator to read the pip list into a dataframe:

It is not easy to understand what is going on. When you say:

Till Yesterday all this commands were working perfectly, but today it was not working, the first error I got is

unexpected error: valueerror: not enough values to unpack (expected 3, got 1) robot

The first thing you need is to identify where that error is coming from. Maybe the omitted lines before the error, could help to do that.

One problem I see in this (strange) way to install and run robot, is the fact that you do not set specific versions for the packages. If a new version of a package causes and error, then you may be in the current situation.

Your logging artifact seems to be incorrect. Can you try this:
