convert_sum_to_guage() not working as desired in transform type processor configuration

[debashish-github]

Hi,
My application emits prometheus metrics and I am using a custom collector to convert this to open telemetry format . I have created the custom collector that includes the transform processor . I have attached my configuration . Basically I wan't to transform my metric ( which of type sum/cumulative and is monotonic) to guage . But the conversion of this metric to guage doesn't happen and neither does it say the reason . I have attached my collector configuration . Below are the prometheus metric and the converted open telemetry metric that I wan't to convert to guage
Prometheus Metric
