Travis failure on UT 'go mod tidy' command

I have a golang repo in which go version is 1.16.10. travis build is failing because of the below error on make_task UT.

main.go:31:2: missing go.sum entry for module providing package github.com/operator-framework/api/pkg/operators/v1 (imported by github.ibm.com/alchemy-containers/ibm-ocs-operator/v4); to add:
	go get github.ibm.com/alchemy-containers/ibm-ocs-operator/v4
main.go:32:2: missing go.sum entry for module providing package github.com/operator-framework/api/pkg/operators/v1alpha1 (imported by github.ibm.com/alchemy-containers/ibm-ocs-operator/v4); to add:
	go get github.ibm.com/alchemy-containers/ibm-ocs-operator/v4
main.go:33:2: no required module provides package github.com/red-hat-data-services/odf-operator/api/v1alpha1; to add it:
	go get github.com/red-hat-data-services/odf-operator/api/v1alpha1
main.go:34:2: no required module provides package github.com/red-hat-storage/ocs-operator/api/v1; to add it:
	go get github.com/red-hat-storage/ocs-operator/api/v1

In local everything is working as expected and on travis also other tasks are running fine. How can I debug the issue?
