I just had the same error today.

I fixed it when I realized that yahoo finance uses BRK-B instead of BRK.B on their page.

See https://finance.yahoo.com/quote/BRK-B

Hi all, thanks, yes, as @YannickDot said, there is no such symbol BRK.B on Yahoo and you probably meant BRK-B, so, the error:

Error: Uncaught (in promise) Error: No data found, symbol may be delisted

is accurate. Chart API works fine for sybols with dots / periods.
