Parameter 'limit' for getAllQueryInfo must be positive. Got

Error message

Parameter 'limit' for getAllQueryInfo must be positive. Got %d.

What it means

Request-parameter validation in the queries REST endpoint: the 'limit' query parameter of GET /v1/query (getAllQueryInfo) was supplied as zero or negative. Limits must be positive because they bound the number of returned query states; the actual value is formatted into the message.
