The error is caused by not having the library files required for OpenTelemetry support in the classpath. A defect has been logged for this - BW-19862. To resolve the issue, apply one of the workarounds given below.

1. Add %BW_HOME%/lib/palettes/otel to tibco.env.STD_EXT_CP in deployed application .tra file and restart the application

OR

2. Redeploy the application. BW_HOME/bin/bwenigne.tra has the entry %BW_HOME%/lib/palettes/otel in tibco.env.STD_EXT_CP so any new deployments will add it to the application .tra file.
