Error 500 when linking dataset with datasamples

Error 500 when linking dataset with datasamples

Closed this issue 4 years ago · 0 comments

It seems that there is first an error in the chaincode and that then this error is not properly catched in the backend, raising a new exception.

It can be reproduced using this end to end test: Substra/substra-tests#106
