Cannot connect to RC api using powershell

Cannot connect to API using my powershell script. It looks like it connects but then when it starts running through the AD portion of my script it errors out with this error:

t C:\PSAutomations\RCUpdateInfoV3-test.ps1:36 char:17

Try add the Content-Type and the Accept headers to each API request.

# Fetch User info from RC api
$AllUsers = Invoke-RestMethod ($RC_SERVER_URL + "/restapi/v1.0/account/~/extension/?perPage=1000") -Headers @{
    Content-Type = "application/json"
    Accept = "application/json"
    Authorization = "Bearer $access_token"
} -Method Get

Still getting same error after changing the code

below is an excerpt from the code with the changes you suggested.

# RC authenticate and obtain access token
$response = Invoke-RestMethod -Method POST -Uri ($RC_SERVER_URL + "/restapi/oauth/token") -Headers $headers -Body @{
    grant_type = 'urn:ietf:params:oauth:grant-type:jwt-bearer'
    assertion = $RC_JWT_TOKEN
}

# Extyract Access Token
$access_token = $response.access_token

# Fetch User info from RC api
$AllUsers = Invoke-RestMethod ($RC_SERVER_URL + "/restapi/v1.0/account/~/extension/?perPage=1000") -Headers @{
    "Content-Type" = "application/json"
    "Accept" = "application/json"
    "Authorization" = "Bearer $access_token"
} -Method Get

Maybe you can try this

# Fetch User info from RC api
$AllUsers = Invoke-RestMethod ($RC_SERVER_URL + "/restapi/v1.0/account/~/extension/?perPage=1000") -Headers @{
    "Authorization" = "Bearer $access_token"
} -ContentType 'application/json' -Method Get

Same issue again.... I am about to give up on Powershell and try this with Python. Would you have any suggestions on how to connect with JWT token using python?
