hey @zaheeratwork, seems that updating gatsby-plugin-react-helmet to ^5.17.0 solves the issue

[CyberHippo]

Updating gatsby-plugin-react-helmet to ^5.17.0 did not work for me but adding deepmerge as a dependency solved it. Solution based on this comment.

Adding deepmerge solved the issue for me when building medusaj gatsby front service in a docker container
