Error when using findpeaks for different limits

Hi

I have a script identifying peaks in a curve (EFFEKT). The following part of the script smoothens out the peaks; if there are several peaks close to each other (not going below the limit (Abonnemang) in between), it displays only the biggest.

My limit was initially set to 24200. I want to check the peaks for the limit 23200, 22200, 21200 and 20200.

24200, 23200 and 22200 works fine, but when I set Abonnemang=21200 I get an error after a couple of minutes The plot for 21200 is shown below.

clear all
load EFFEKT

dt = datetime(2021,1,1:1:365);
 et = hours(0:23)';
 t = repmat(dt,length(et),1) + repmat(et,1,length(dt));
t=t(:);


Abonnemang=21200;
for x=1:numel(EFFEKT)-1  %IF THERE IS SEVERAL PEAKS IN A ROW, TAKE THE BIGGEST
    [max_val,locs] = findpeaks(EFFEKT,'MinPeakHeight',Abonnemang,'MinPeakDistance',x); % find the peak and its x axis location
    [t0_pos1,s0_pos1,t0_neg1,s0_neg1]= crossing_V7(EFFEKT,t,Abonnemang,'linear'); % positive (pos) and negative (neg) slope crossing points
    peak_width = t0_neg1- t0_pos1;
    if length(max_val)==length(t0_pos1)
        break
    end
end

for z=1:length(EFFEKT) %MAKE THE LIMIT A LINE
AB(z)=Abonnemang;
end
