When I try to get the graph for a custom metrics I instrumented using Prometheus I got the error "msg="append failed" err="expected equal, got \"INVALID\"". Why this occurs and how to solve this?

    Can you please post your application config/code and your prometheus server config? – Oliver Apr 10 '20 at 13:07
  • Today I was able to figure the root cause for the issue. This has occurred due to a parsing error I have done while converting the metrics into Text format after extracting them from the Prometheus Default registry. – N.Chandimali Apr 10 '20 at 13:56
  • @N.Chandimali please put your solution here so others can use it. – AminSojoudi Dec 30 '22 at 07:47
