This is preventing me from progressing further in the tutorial. I also tried Chrome, but the same issue shows. I've checked that cargo +nightly contract build runs without errors and all tests pass.

Any ideas on what I could be doing wrong?

i met same problem
Last Saturday, i build example flipper project, it works well
But today i rebuild it, then upload contract caught same error

Previous flipper.contract is language":"ink! 3.0.0-rc7
Today's flipper.contract is language":"ink! 3.0.0-rc8
