All browsers have a URL limit of about 2050 characters for their length which is being exceeded within a Client-side Formula when you receive this error message. Client-side Formulas make a REST API call to perform their calculation/action so this means we need to pass any changed data values on the form as part of the REST API call. So this error message can occur when:

  1. When you have a large description field (2000 characters+) where the user enters in lots of data and then when the Formula triggers the data in this field exceeds the URL length limit.
  2. When you create one record from another and a significant number of fields (around 40+) have default values so that the combined total exceeds the URL length limit.


In order to work around this limit, we have two methods:

  1. Method 1 (using POST)
  2. Method 2 (using GET and Clientside Payload)
