As Michael & Stahorszki mentioned
"B"
must be capital
Property : spring.servlet.multipart.maxFileSize= 50MB
In Yaml
spring:
servlet:
multipart:
max-file-size: ${MAX_FILE_SIZE:8MB}
max-request-size: ${MAX_REQUEST_SIZE:8MB}
Today I have repeated this error, althought I set "MB" with capital "B":
Description:

If I comment out this options application wouldn't start anyway - there are some errors in the spring context. So I think it is a wrong error message then context cannot be created + multipart options are given.
In my case, I had redundant whitespace at the end of size (after MB, KB). To fix this, I deleted the space.
Remove the space as well after 50MB, I faced the same error but due to space after value attribute
