Using the Resize NSX Edge Node script fails with the error "Failed to get Bearer Token!"

Issue/Introduction

The KB for NSX Edge node resize tool (VCF deployed NSX environments) - https://knowledge.broadcom.com/external/article/312196/ , is being applied. 

During the script implementation we encounter the error "Failed to get Bearer Token!". The error stack looks something like the below -

^{root@sddc-M [/home/vcf]# ./resize.sh --edge-cluster <Edge cluster name> --user <ssoUser> --password <ssoUserPassword> --form-factor LARGE}

^{Resizing Edge nodes in Edge cluster <edge_cluster> to form factor LARGE}

^{The Edge Node Resizer tool takes Edge nodes offline one at a time in order
to recreate them with a specified form factor. This means that}

<sup>* Each Edge node's Tier-0 interfaces temporarily go offline during resizing
* Tier-1 router services relocate from one Edge node to another</sup>

^{This may lead to temporary network traffic interruptions during the resize.
The full resize operation may take as long as it did to originally create
and (if requested) expand the Edge cluster.}

VMware Cloud Foundation 4.x
VMware Cloud Foundation 5.x

Cause

This issue occurs if the tool is unable to accept the specified SSO password that contains special characters. (Most case scenarios '$'.)

Resolution

Use quotes to specify the password -

./resize.sh --edge-cluster <Edge cluster name> --user <ssoUser> --password '<ssoUserPassword>' --form-factor <SMALL,MEDIUM,LARGE,XLARGE>

^{root@sddc-M [/home/vcf]# ./resize.sh --edge-cluster vcf_edge01 --user [email protected] --password 'VMware123$' --form-factor LARGE}

OR

Run the command without the password attribute, which will then request the user to enter the password manually during the script execution -

./resize.sh --edge-cluster <Edge cluster name> --user <ssoUser> --form-factor <SMALL,MEDIUM,LARGE,XLARGE>

^{root@sddc-M [/home/vcf]# ./resize.sh --edge-cluster vcf_edge01 --user [email protected] --form-factor LARGE}
