i think in the else case, we can just encode it as bytes and upload it.

so that we can instruct the agent to "write the answer of 2+2 to ipfs", then it'd pass "4" to this function, and we'd just upload it as plain text.

Can we include some tests for the testing through the behavior and correctness of the upload function?
