Hello,
Since the beginning of the week, the workflows executed by a service user are not running anymore and failing with the following error.
431: Request Header Fields Too Large
at MetricsClient.query (file:///opt/sdk_modules/@dynatrace-sdk/client-classic-environment-v2@4/esm/index.js:14847:21)
at eventLoopTick (ext:core/01_core.js:177:7)
at async computeAvailabilityFor (file:///script.ts:118:20)
at async default (file:///script.ts:21:9)
The failing API is the following : `/platform/classic/environment-api/v2/metrics/query?metricSelector=builtin`.
The same workflow is executed without issue with a "standard" user. The issue is only happening with service users.
I've read the Error when running DQL Query through workflow but do not know how to restrict authorizations for a service user and don't understand why it is suddenly failing as it worked without problem since 2025.
Are you aware of any change for the workflow or any permission required for the service user ?
Thanks.
Florent
