ICON method debug_estimateStep

Good afternoon. After update 10.16.2021 the restapi method debug_estimateStep stopped working. When executing query using json example from documentation - returns
error: {
code: -32602,
message: “JSON schema validation error: ‘params’ has an invalid value”
I take example for query from this link

Has anyone had a similar problem with this query and how have you solved it?

Yeah… we are aware of this problem.
We will fix this issue and publish new update release soon (by next Monday).
In the meantime, please use the official citizen node (https://ctz.solidwallet.io) for debug_estimateStep method.
Thanks for your reporting.
