No updateMany() query

[Ameya7496deshpande]

Trying to update multiple documents by passing/trying to pass aggregation string in .with().
The string passed is something like: "[{$set: {filed1: {$multiply: ['$filed2' : 90]}}}]"
I get error message as : "Replacements can not be multi".

If query is modified like : "{$set: {filed1: {$multiply: ['$filed2' : 90]}}}"
Getting error : com.mongodb.WriteConcernException: Write failed with error code 52 and error message 'The dollar ($) prefixed field '$multiple' in 'filed1.$multiple' is not valid for storage.'
